This troper seems to have the ability to only do this by accident. When I don't intend to, I can walk into a group of people having a conversation and they'll never notice me until I say something. After seeing how good I am at doing this without even trying, I figured that if I actually do this on purpose I could be a master at it. No such luck however, as whenever I actually try to walk in unnoticed, someone always sees me. Ah well

.........People forget that I am in the room. and don't realize if I enter or exit. I have had people start talking about me because they did not think I was in the room. and try to talk to me not realizing I have left. Because of this, it often seems like I do this.

...Canada, is that you?

This Troper does it regardless of if he wants to or not.

My friends say I do this a lot. I apparently pull off Stealth byes all the time without even trying. Once we were all sitting at a table eating and I left, when I came back everyone exclaimed that I had "batman"ed my way out of there in broad daylight. I had only gone upstairs to get cookies...

Pulled this off. While speaking with a police officer. But I've practiced this very often and more than once I screwed up.

This troper knew a guy who, despite being a very large young man, snuck away with such frequency that we started calling him a Fat Batman.

This troper has found the easiest way to disappear from a group when walking down a corridor is to walk in the back staying quiet, and then duck down another corridor while they are in deep conversation.

This troper likes to do this, to annoy people. It usually works.

Apparantly, me. I don't understand it, I was clearly walking behind them for a good block or so, but freaked the shit out of a group of my friends when I decided to speak up.

I've got a reputation of {{Stealth Hi Bye}}s, that it's gotten to the point of lampshadehanging. New friends beware, you won't get used to me until I've walked out of a classroom saying "Hey buddy", only to reappear coming out of one of the bathroom stalls in the restroom. Which was in the other direction I was heading. Justified that I was tired and the Teacher sent me for a revitalizing walk. That just so happens to involve taking a walk outside. But, I mean, come ON, how slow do they walk?!

Since people (even friends, sadly) tend not to pay too much attention to this troper, she's able to do this without trying. Some of the dimmer ones will say "[Troper Name]! When did you get here?" after she's been standing there talking to people for at least 10 minutes. FailedASpotCheck much?

People often jump at me for suddenly appearing in front of them. And I have to tap their shoulder just for them to see me.

During freshman year of college, this troper wore a large pair of boots without the laces, because although they'd broken, the boots still stayed on just fine. The boots clomped, the eyelets jingled, and yet I '''still''' managed to disappear my 6'4", 250lb self when the time was right. I may even be the Fat Batman mentioned above, I don't know.

This troper doesn't do the "bye" part much, but the "hi" part is very popular with him. His footfalls can be absolutely silent even on dry grass if he tries, and when he sees someone he wants to talk to, or simply wants to insert himself into a group, he'll simply walk up. Even if he's at a 90 degree angle from his target's eyes, he can be completely unnoticed, despite being 6'4. He once went up behind his friend to compliment her on her dye job for ''A Midsummer Night's Dream'' while she was on the makeup stool and she screamed and nearly fell off when she saw him behind her, as he waited for her to finish her conversation.

Ditto here; the "bye" part isn't nearly half as rewarding.

Same here. This troper walks softly and makes no sound while breathing (except during allergy season maybe.) Thus he often skulks around without even realizing it. More than once he's started talking about some mundane matter with coworkers while they had their backs turned, only to see them jump out of their skins.

This dude's footsteps are silent, for no apparent reason. Because of this, no one notices him until he says something. Sometimes, it looks like he's been "creepin'" on the group, unintentionally, of course.

Usually, this troper has a chronic inability to sneak up on ''anyone'', no matter the circumstances. However, partially due to my excellent ability of navigating through crowds, and really fast walking, I've managed to pull this quite a few times on people.

This Troper has an ability to perform StealthHiBye GLOMPS to people! Yes, it be awesome.

Despuite being tall enough to see over the cubicles and, I've managed to do this unintentionally to about half my department... ''In the last week.'' I'm seriosuly considering wearing bells so people know I'm coming.

Truth truth truth. Apparently I have the ability to 'teleport', or at least startle the shit out of people who I expected to know I was already present. I've gone through this with every new roomate, coworker, boss, significant other, insignificant other, and it's long past funny to have people spazz out in surprise when they notice me in the room.

This troper can do this as well. When asked about it, I said I was a part-time ninja. "But I can see you!" My reply: "PART-TIME"

This troper walks silently and doesn't generally announce his presence, so he regularly ends up doing this to friends, to the point where he has a reputation for it. His natural walk is also very fast, so he has on more than one occasion baffled people by walking away in one direction and - entirely without intending it - emerging from a door behind them a very brief time later.

One of this troper's friends who plays the ''{{Discworld}} MUD'' uses his ninja training to leave in the middle of conversations. And appear in rooms I thought were empty.

For some reason, This Troper has the ability to move silently in a full sprint, even while wearing heavy boots. One time, he zipped up behind two co-workers across a vinyl tile surface without making a sound. When he started speaking, one of them turned around, visibly startled. This individual remarked that he was "Like a ghost!" On the flip side, he has a tendency to lose track of people very easily if he takes his eyes off them to indulge in staring off into space for even a moment. Very often, he'll be following them and they'll fail to notice when he inadvertently stops doing so, even after going a good hundred yards outside his field of view.

This Troper has both done this (she calls it "Ninja'D") and had this happen to her. The former because she is short, carries herself in a manner that doesn't garner attention, and usually stands there listening to a conversation until she speaks up, scaring the bejeezus out of her friends; the latter because she gets very carried away in whatever she's doing at the moment and doesn't notice somebody standing right next to her until they say something.

This troper managed to accidentally pull one of these on a friend while they (and about 10 others) were at dinner. What makes this amusing is that he had been assigned to kill me in a game of Assassins, and thus was watching me so he could follow as I left. The kicker? He told me about this while we were leaving a showing of ''TheDarkKnight''.

This Troper has accidentally done this numerous times in the comic book shops he went to. Like some of the others here, he was referred to as a ninja.

This troper frequently pulls these on her mother, classmates, roommates and other people, though not on purpose. She's a just very quiet person and apparently has very light footfalls. My current roommate is actually legally blind and doesn't really have any peripheral vision, and I've pulled this enough on him that we've joke that I should start wearing bells.

I pull of Stealth His fine, but I'm not so good at Stealth Byes. Of course, the only reasonable thing to say after you've managed a Stealth Hi is "I'm Batman."

No, the only thing to say is "I Am the Night!" Even IF its day time.

This editor (who pulled SHB multiple times, intentionally and not, and was once told he is like a ghost despite being big and heavy) finally came to the conclusion that most people simply don't freaking pay attention to what is going on around them. Background noise (heavy traffic or somesuch) definitely helps but puh-leeease...

Once, during one of this troper's boyfriend's attempts to get him to join him in his daily naps, he managed to slip out of his mate's arms and slip in his mate's big tiger plush, ninja-style. His mate had no idea the switch took place, and was mighty surprised to wake up holding the stuffed animal, instead.

This troper is a member of a small group of people capable of Steath Hi Bye. Some have theorized that This Troper's ability come from the lack of a soul. His friend is capable of doing this being a 6'7" oaf.

This Troper once had a roommate who was able to do this all the time. The roommate was getting his grad degree in psychology, and he enjoyed pulling it on This Troper as an advanced form of applied psychology. His honest grin always made it impossible not to laugh with him about it instead of getting angry, though.

This Troper can do it, if he holds his keybunch (S'got a keybunch at work for safes and tills etc.) and when he bends over (taller than the average man) and whispers "I'm a ninja." it scares people. Also when people turn around corners they tend to get frightened. It does help that this Troper's standard behaviour is loud, bombastic and more Sir Brian Blessed than meek little mouse.

This Troper has a reputation for doing this. It got to the point where I lampshaded it personally by going as a ninja to a Halloween costume party last year and specifically attempted to scare the hell out of everyone I knew by popping up right behind them and greeting them. (It was a pretty crowded party, so it wasn't too difficult.)

This Troper doesn't agree with the assertion that practitioners automatically know that they're doing it. I'm 6'2" (180 cm for folks who use rational measuring systems) and tend to walk fairly rapidly. Nevertheless, when I was working as a carhop, I would startle an average of a customer a shift (maybe 2. I think my high was 5) with a Stealth Hi. One time, I swear to G* d the customer was actually looking at me and she still jumped when I tapped on the window to take her order. I'll admit I've occasionally done it deliberately, but not ''that'' often...

This Troper was called "Nightcrawler" by a bunch of friends for his ability to appear and disappear from out of no where. Helped that I was taking German and spoke with a decent Munich Accent when I wanted too.

This troper occasionally pulls this off, sometimes by accident...

This Troper has been banned from walking around her house barefoot due to several instances of nearly giving parents heart attacks due to SHB. The kicker is that she still goes unnoticed both coming and going, whilst wearing heavy steel toe-capped trainers and not making any effort to be quiet. It's even more annoying when said comings and goings involve going in or out of a front door which slams, and can't be opened without at least one dog taking vocal notice.

This Troper does this all the time. Unintentionally. She also manages to go on trips with friends to various places she has never been to in her life. This Troper suspects that a) people don't pay attention; b) that she has a doppelganger; c) that she is unconsciously able to turn invisible; or d) any combination of the above.

This troper has a friend by the name of Lucas who is the unintentional master at this. His adeptness of the "ninja vanish" is noted amongst many of his friends, especially in defiance of his routinely shock-blond hair and flamboyant dress style. The thing is, he fails miserably at this whenever he tried on purpose. One time, Lucas, our mutual friend Wayne, and myself were all at the airport waiting for Lucas' then-girlfriend. Lucas was dressed in all bright red, and had recently dyed his hair to a near-white. Both me and Wayne were looking right at him, when someone passed in front of him, and... no Lucas. Despite him being the most obviously-dressed person in LAX, it was like he was never there. It took the two of us another couple of minutes to find him again.

This troper frequently startles her friends by doing this. I'll join the group in the middle of a conversation, but I don't interrupt by saying hi for fear of being rude. But then I sort of forget to mention that I'm there at all...and when I say something, everyone is startled. Sometimes it even takes a while for them to find me. Reaching the not-so-enormous height of 4'10", my six-foot-something guy friends tend to look right over me in confusion.

This tropher has a reputation for this. It got so bad that my last girlfriend bought me a belled collar so I wouldn't sneak up on her. It didn't work.

This troper has had the reputation for doing this through all four years of high school, and (so far) two years of college. Highlights:

In Sophmore year of high school, I walked into the band room after school, right behind my best friend. We took our seats, and the conversation started up. Since I'm TheQuietOne, I didn't say anything. Half an hour later, I finally participate in the conversation, and my friend nearly had heart attack. He thought another friend of his was right behind him.

In Junior year, I had my (future) girlfriend convinced that I was a ghost.

In Freshman year of college, some friends were eating lunch on the steps right outside the student store. I got my lunch, and took my seat next to a lamp post next to the steps, right at their eye level. When I finally spoke up, everyone got scared and pissed off. One friend went into the store in order to buy me some tic-tacs, a la {{Seinfeld}}. It didn't work.

This troper is known for unceremonious entrances and exits to the point where people joke that he appears and disappears out of thin air.

This troper is apparently is a master at this. His step mother once said that he would give her a heart attack from appearing out of nowhere, and his actual mother once got called him out on his habit of leaving the room whenever she looked the other way, even though neither was intentional.

I do this all the time at work. I've been threatened to have a bell put on me many times now.

This troper is big, tall, strong and fat. Mostly fat. Despite the size, nobody seems to see or even hear him when he walks, leading to loud screams, jumps and, my favorite "What the-holy-f* ckin' hell, man?"

This troper's a bit of a real-life Ted in this respect. In spite of being almost six and a half feet tall, weighing in at just over 210 lbs., and completely lacking in any kind of stealth behavior, he always seems to take people by surprise. It never seems to occur to anyone to take notice of me until I start actively asserting my presence. Either AwesomeButImpractical or CursedWithAwesome, depending on what kind of mood I'm in.

This troper has unfortunate stealth skills. Walking up to a friend and saying hi gives about a 50% chance of scaring the crap out of them. Well, or I'm just hideously deformed...

This Troper somehow has these skills. Since she's heavy and quite klutzy she has no idea how people ''can't'' hear her. As for the bye part... Well, her father tells her frequently that she's "Really fast for a fat kid."

This Troper hates wearing socks and shoes , and uses only the front half of his foot when walking barefoot(It's more of a lope really). Once, I went to the bathroom, sneaking by my family in the process, then back into my room, escaping the notice of ''everyone'', including the person sitting at their desk 5 feet away. They thought I was halfway across the house when they wanted to talk to me about something.

In the last few homes this troper has lived in, the floors tend to creak when walked on. Since I'm very overweight, this tends to make me rather nervous; so, I've gotten into the habit of walking as lightly as possible wherever I go, being careful not to put down too much weight. However, on numerous occasions I've managed to startle my parents (and some other people, but mostly my parents) when I speak up to get their attention, and I'm told that I need to make more noise when I walk.

This troper was at camp once, chatting with his cabin-mates, when one of them came back from the bathroom. None of us had noticed him leave. We immediately concluded that the person in question was a ninja.

For This Troper, it's an unfortunate side effect of poor social skills an probably gender too; Girls having a tendency to group quickly + being too shy to break into said groups = being able to approach, standing nearby and leaving without being noticed.

This troper has been on both side of this trope. To the point of ensuring to make noise while walking.

This troper, due to being TheQuietOne, has an unfortunate tendency to pull this trope completely by accident. I'm frequently amazed that people don't notice a six-foot, 240 lb. black male's presence unless he straight up announces it. Even when I do, apparently my normal voice is so soft that people really don't hear me.

This Troper does it naturally, regardless of whether he's conscious of doing it or not. It helps that he's been TheQuietOne his entire life and has an odd habit of walking on his toes. Admittedly, he does tend to do the Stealth Hi more frequently than Stealth Byes.

This troper has a habit of doing this. The years of trying to avoid her parents and staying up past bedtime have taught her to be quiet and sneaky, which has really come in handy when she wants to surprise her friends or stay unseen by the teachers who want to speak to her about skipping assembly/homeroom.

This troper commonly (and unintentionally) commits the "ninja peekaboo" variety. When walking anywhere with friends, she automatically and silently ducks to the other side of the friend (or group) to avoid obstacles. People often notice that she "disappeared" first, ''then'' jump when they find her on their other side. She generally deadpans that she can teleport, though she figures it's because most people aren't as observant as she expects them to be. Being TheQuietOne can also lead to Stealth Hi situations - sometimes if the mood takes her, she'll exploit it for laughs.

This troper's friend commonly refers to her as an elf, due to the sheer number of times this troper has been able to sneak up on various people (including said friend) without making a sound. Conversations are often prefaced by, "DAAAHH! Hello. Where'd you come from?"

this troper just like the many others has the whole 'I'm so big it doesn't make sense to be so stealthy' thing, however he pulled this trope off quite a bit back in high school and would a few time purposefully subvert it with psycho breathing effectively making it something simmiliar to a {{alone with the psycho}} moment, quite fun really

This Troper apparently does this often, even ''with'' the Tripp pants that have jingly broken chains on them. However, she has a rather memorable one in the eighth grade, lacking the "bye" part. She had approached one of her classmates from the side, leaned against the table while he was talking with some other classmates. He had earlier dropped a comment about me being psychotic or something along those lines. As soon as he stopped talking, the following exchange happened: #QUOTE# '''Troper''': "So who's the psychotic one now?" #QUOTE# '''Unfortunate Victim''': *turns, sees her sitting there when she ''wasn't'' five seconds ago* "GAH!"

This Troper has yet to scare anybody out of their skin, but has a reputation in his dorm for being very quiet. He will regularly join his friends in the lounge without their noticing and leave just as quietly. He blames it on living in an almost 100 year old house with squeaky floors, and a mother who wakes at the drop of a hat and then comes into the bathroom to make sure you aren't your sleepwalking sister. He learned to be very quiet at a young age.

Ryumaru: I looooove doing this. Especially to my sister. It's rather entertaining, the way she jumps and shrieks.... I once snuck away from her on the walk home, in broad daylight. Cue the "How TF did you get there?" look from her when I was waiting at home.

This troper can inexplicably sneak up on people when walking up to them normally. I suspect everyone does this some time or other.

This 6'5" Troper accidentally does it all the time.

Same here ('cept I'm 5'4''), but I do it on purpose just as much, mostly with my brother.

This 6'1" Troper has done to just about everyone he has met, including his former Army Captain father

This Troper does it by accident, generally by just walking up to a group of friends, sitting down with them, and not announcing her arrival. Rest assured that at elast one of them won't notice.

This Troper learned (in marching band) that 'rolling' your feet allows you to walk pretty much completely silently, which allows the use of this trope '''even through doors'''. It's great fun.

Cool. I learned it on my own.

This troper walks fairly lightly, so she has to make noise intentionally so as not to freak folks out sometimes, especially if they're an avid listener of too-loud music.

This troper used to do this in highschool and earned the rather amusing nickname "Jesus!" because that's what people yelled when I popped up behind them.

Interesting variation in that I never notice what is going on around me; my mom thinks my eyes got worse, but the doc confirms no and agrees with me in that I'm simply oblivious. Which is why it seems to me that ''everyone'' is pulling a Stealth Hi Bye on me when they really weren't trying.

Apparently, I do this a lot without trying. And now my boss is scared to page me since for all she knows I'll pop out of a cash register asking what she wants. And of course the rest of my co-workers to a lesser extent.

Everyone in my family but my mother is a master at the bye part, only I've gotten the hi down.

I apparently do this, but I rarely mean to. My mum is so oblivious that I startle her in this manner ''all the time'', can't keep a straight face, and get yelled at for it. Often, I try to subtly announce my presence and nobody notices, forcing me to startle them. Or... basically, I don't do this on purpose! It just happens. And now my roommate regularly accuses me of being a {{ninja}}.

This Troper does it quite often and rather easily. I seem to have a good move silently check...

This troper often pulls them on her family, since she likes to go barefoot at home and thus barely makes noise when she walks around.

This Troper is very much a Stealth Hi Byer. No 'Batman' nicknames, though - but Hawley Griffin was not so lucky...

This Troper does it both ways, and sometimes mixes them up for weird results. Like going out for a smoke in the middle of class, then come back to find that nobody noticed I ever left. I'm also one of those cases of nonsensical stealth. I mean, I dress like a Neo wannabe and have a constant cough. It seems all those HighlyVisibleNinjas were right after all...

This Troper apparently has a talent for doing this to my new housemate. It's not even intentional, it's just that I walk quietly and he isn't used to sharing an apartment, so he freaks out whenever he turns around and I walked into the room when he wasn't paying attention.

this troper once startled herself one day when she realized she couldn't hear her own footsteps. Cue me trying to walk "louder" but failing. I've also scared a man shovelling his walk when he turned around to face me and i said hi. I've done this to several friends and it's a favourite thing to do in drama class as well (especially when we are not supposed to wear shoes).

This troper would like to mention that being nearly six feet tall with flaming red hair and a tendency to wear red shirts does not seem to hinder his ability to appear behind people and give them heart attacks. Neither does the fact that I sound like a herd of rampaging elephants when I run, and I run ''everywhere''.

This troper's friends have gotten used to my ability to do this, so when they notice me they always keep quiet until someone else notices, just to see their reaction. It is quite amusing, especially when I can manage to sneak up on someone along a mile-long, dead straight road ''without trying to''.

This troper is not only painfully shy, but also has very sensitive ears, so she learned from a very young age how to do things while making minimal noise. This includes walking, opening doors, moving objects, sitting down, and even talking in a way designed to provide minimum interruption potential. Combined with the facts that (a) she is prone to wearing dark-colored coats and black gloves when cold and (b) she has trained in martial arts, it's small wonder that she has gained a reputation as a ninja. There have been times when she has been sitting in plain sight in a room for ten minutes and ''still'' managed to make people jump when she said something. Her friends have also recounted times when she has "Ninja Vanished." And, like many of the people here, she often does it without even trying to.

This troper does this often, most of the time without even trying. She's so good at it, she was thinking of maybe becoming a ninja, before she realized that she isn't japanese and ninja training would most likely be hard to master.

This troper's done this fairly often at work, unintentionally, to the point that I have to speak up when I'm about to walk into someone so nothing's spilled (and even then, as a quiet and tiny person, I'm barely noticed). Otherwise I'm fairly proud of my ninja abilities, as I used to stomp when I walked and got made fun of for it. Make fun of me, and you get stealthed later.

This troper is a subversion: he is possibly the most quiet person in the school, but, whenever he tries one of these, someone decides to look in his direction at exactly the wrong moment, meaning I'm still too far away to get the effect one of these should give.

This unknown tropette often had this happen to her for the sake of laughs. Most often by the biggest guy in school. Oh, did she forget to mention that she is a complete and utter spazz?

This troper walks quietly and has startled her mom, unintentionally, by walking into the room without her mom noticing more times than she can count.

This Troper has developed the habit of coming in to her classroom at school, and, because she insists upon sitting under the table, when someone sits down, they usually kick her. One time, this happened: #QUOTE#'This Troper: (Comes in and sits down under table. Screaming argument going on. Gets out book, which is incidentally Volume Four of the Japanese VampireKnight, although she also has the English and starts reading. Someone sits down and kicks her.) OY! #QUOTE#'Other person: Agh! [Troper Name]! Why do you always sit there! #QUOTE#'This Troper: Good point. (Crawls out from under table in true Beyond Birthday fashion.) It's hard to read Kanji under that table. And my neck hurts.

I did the hi and bye thing to a friend ALL DAY LONG. Most of the time it was unintentionally (I went to the bathroom and, when I opened the door to get out, she was right there and she freaked out because it was like the fifth stealth), but when I realized it pissed her off I started to do it on purpose. Weird part? I'm like 12 inches taller than she.

Also, I don't know why people are so damn slow: Once, I got out of school, went to the mall (that is like three blocks from school), wandered around, bought a CD while taking my time, wandered again, hitched a ride in a motorbike to another mall, got a 2nd degree burn with the exhaust system, talked with the biker, got his number, wandered again trying to find a drugstore to treat the burn without finding anything and, when I was walking to a third mall to get a taxi that would take me home, I found out that one of my classmates was JUST REACHING THE PLACE. Once she saw me, she shouted 'How did you got here so quickly?' and my reply was 'motorbike'. Then she shouted 'I hate you' and I laughed.

This Troper managed to pull one of these off at an Anime convention, ''wearing a Nabeshin costume with an '''eighteen-inch afro.'''''

This Troper, despite being 6'6", lanky, and entirely nonathletic has a strange ability to do this. I can often do it intentionally, to hilarious effect, but it becomes a problem when I'm unsure of how to casually approach somebody who has their back turned without scaring the shit out of them.

Zadia does this quite a bit. I often scare the hell out of people by saying hello to them when they have no clue that I'm there, and several times I'll leave to go get something, return and have someone exclaim that I was just there, then they looked back and I was gone, and then I was there again...

This troper's husband has mastered this skill. As he tags along and serves as TeamDad to the church youth group she advises, the kids are frequently impressed by his stealthy abilities. Since he's also a RedheadedHero, they've nicknamed him "the Irish Ninja."

This troper seems to be this without trying, sometimes, she'll just be walking down the street with some friends, and when she says something to contribute to the conversation everyone freaks out because no one knew she was there. She's also done this in any house, when she goes to ask someone something and they're startled or freaked out she's there. Even though she stomps a little when she walks, '''and even on houses with creaky wood on the floor'''. Whenever she tries to do it on purpose, however, she's always seen.

This troper as well, to such an extent that this trope was played straight with him in a student film in his high school film class, to uproarious laughter.

This troper was accused of doing it quite a few times. More than once he walked inside a room and after a few minutes people go "Grandy... how long have you been there?", that is, if they don't simply jump when he sneezes.

This troper was known for this in high school-he'd wander on up as though he'd never heard of stealth in his life, and people would be shocked to see him suddenly standing next to them. This stopped after I went to college. It may have something to do with occupying a slot in the social hierarchy vaguely similar to Ted; since no one particularly expected me to be anywhere, suddenly enforcing my presence with my existence came as a surprise.

Sometimes, this troper will walk up behind someone to say hi, and they'll be opening a locker or something, and I'll just say hi and apparently they didn't here me come up. At all.

This troper can get away quickly if she doesn't want to be stuck with chores. Does that count?

I swear my brother's a Ninja. Sometimes, he'll be in the house but I never see him come in. Also, He is gone for most of the day.

Tropers/SunnyV does this a lot, totally by accident, to her parents. Usually though, she'll walk up to one of them and start talking, and they'll fail to realize she was there, and hilarity will ensue.

Tropers/Tidal_Wave_17 does this so much that he has gained a nickname by fellow students: "The Creeper". Strangely, whenever he ''tries'' to sneak up on people, he makes so much noise you ''can't'' help but notice him.

I have a tendency to do this at work, usually walking up behind or next to someone without them noticing, and they're startled when they turn around and see me or when I say something. I've been called a ninja by a few co-workers, and one constantly mentioned that I should wear a bell so they can hear me coming.

Despite being a five foot six, two hundred sixty pound "brick outhouse", I can pull this off rather frequently. Some of my friends hypothesize it's my overall "don't mind me, just a shadow" posture that helps people ignore me.

This Troper has a tendency to walk up to people and stand next to/behind them for a while without them noticing. One of my favorite examples is when I was shopping with some friends, went to a different part of the store, found them again, and then stood behind them for about a minute before they noticed me. What makes it even better was one of them looked right at me when I first walked up to them but was still surprised when I was noticed later.

Tropers/{{Excel-2011}}. I do this all the time by going right behind people and waiting for them to turn around. In one instance, the scream was heard through the entire packed auditorium. The trick is to wear the right footwear and control your breathing. A SlasherSmile like the one I have perfected over the years is optional, but greatly enhances the effect if you can hold it long enough or time it properly.

This troper pulled one off recently without even trying (mind you, he's six foot six, 250 pounds). Wearing squeaky boots. In a hallway. He considers it his CrowningMomentOfAwesome.

This troper is at least six foot one tall, yet he is quite good at getting unnoticed (he describes himself as "invisible, except for the people who want to see me"), so this kind of thing is usual to him - a classmate even decided to show up behind him one day in response. In addition to getting someone scared when revealing his presence (at a certain point he started to reply with "I cause this on people").

This troper does this frequently to her mother, albeit unintentionally since I don't make much noise when walking, my mother complains about this and asks me to do noise when I enter a room so I won't startle her.

This troper doesn't even has to try to pull this off. I have actually startled cats, the sneakiest animals of them all, by ahemming them when they don't realize I'm within kicking distance of them.

This troper is ''friggin' awesome'' at doing these. Mostly unintentionally, though...

Tropers/{{Unshavenhobo}} I started doing this to mess with people when I figured out how to sneak around. I'm also >6 foot tall and wear size 15.5 shoes and still somehow manage to be Mr. Cellophane occasionally...

My father is 185 cm (~6'1.5"), about 120kg (265 pounds) and 52 years old (31.03.2011). One rarely hears him coming. Rottenvenetic

This troper's female friend loves to pull this trick off. And she's baaaad at it.

This Troper love doing this. Apparently my friends like doing it as well and we have created the 'ninja game'.

This troper's dog used to do this. The thing was, said dog was 120 lbs of clumsy, dopey, lovable chocolate lab, who was normally not given to any sort of grace or subtlety. But every once in a while, I'd be sitting in my room, watching TV, only to look back and see him sleeping on my bed, and have no memory of him ever entering the room.

This troper's known for being stealthy. He made a habit of sneaking up on people at his old job, just silently slipping up behind them and whispering "Boo" in their ears. He still surprises people at how quietly he can just disappear and then return to his desk at his new job. When questioned, he explains his ability thusly: "I'm part ninja."

This troper often does this without meaning to, usually to her sister. More often then not, this troper will leave her room to go to the bathroom and will be noticed on her way back earning a "How'd you do that" reaction from her sister. It helps that this troper walks very quietly, quickly and on the balls of her feet, which creates an even lighter footfall.

My younger sibling manages still, at 12 to do this undetected. Especially when I'm absorbed soley in the world of the internet. She'll come up behind me and go "BOO!" and i'll screech like hell.

This troper does it from time to time. Occasionally, it's by accident, since I thought people knew I was there, but other times, I do it deliberately, give the inherent humor in startling people.

This Troper has had a habit of appearing without a sound, usually to the side of or behind people. When he feels like having a laugh, he just stands there, like a shadow... ''jesus, where did you come from?!'' It never gets old. He often does this (unintentionally) to his mom, appearing in rooms she had believed were empty. Creaky stairs has given this Troper a lot of practice. Vanishing without a trace is something this Troper will only perform when experiencing a Panic Attack, usually due to too many people.

As an extension to this Troper's previous example, it has gotten so bad that this Troper even does it ''online''. He'll be silent/lurking/inactive and will pop in unexpectedly at a really odd moment (typically by mentioning his name or mentioning something he can help with. He tends to respond with "You raaannng?")

I can do this without even trying. My friends have concluded that I must have been part of some experiment where I had cat DNA fused into my body. It doesn't help that I have other cat-like characteristics.

creepy voice* hello there...
