Not sure whether this counts, but putting it here anyway just because. I was browsing YouTube one day... and I found this.

This Troper has a non-videogame example at his local Wal-Mart [=McDonald's=]. Briefly, the cash register automatically gives a Value Meal discount if the meal matches something on the value menu. Meanwhile, if bought outside of a Value Meal, Coke is $1. So, he buys his usual meal a la carte and gets both the $.99 discount for the large Coke and the $.69 discount for the Value Meal. Granted, this does mean I'm penny-pinching McDonald's, but hey, cheap food.

This Troper encountered a random glitch when playing NeoGeo Battle Collesim. When I went to exit training mode as Kyo and Iori, the here comes a new challnger screen came up and all of a sudden I was playing a single player arcade mode game.

This troper found a weird one in Megaman Xtreme. He fell into a pit in a level, but instead of just, you know, dying. The game reset itself. Weirdly, the game wasn't just reset, the colors were all wrong, with a weird border around random sprites that he didn't even know had a border. He continued onward into the game, and found some weirder symptoms. Random areas in the background were pitch black for no reason, X was orange for no apparant reason, and any time anything fired a projectile, the game slowed to a crawl. This was completely epic at the time. Unfortunately, we couldn't recreate it.

This Troper noticed something interesting in her copy of Mass Effect 2; whenever she plays through Thane's loyalty mission and the C-Sec officer mentions the Shepard VI doing its delete-you-on-the-way-to-real-problems schtick, Tali goes "That's pretty extreme, Shepard." Cut to the usual shot of Shepard's rebuttal-- only without the Shepard, who reappears in the next cut. This happens every single time, and this Troper finds it oddly funny.

This Troper (Beta Maxis) found that by partially unplugging the headphones to his iPod Nano, the main music and lyrics were dimmed and let all the background instruments be heard like the harmony and melodies switched n prominence. It makes some songs epic or at least on par with the song played normally, including DragonForce songs.

This is known as Out Of Phase Stereo and can be done very easily with anything that has a headphone jack, so long as you're listening to something that's in stereo to begin with. It can be a pretty neat way to hear background elements of songs you wouldn't otherwise pick up on, although apparently there's a slight risk of damaging your headphones that way.

Inverted example: this troper always was creeped out by the cocoon-things in the Creature mode of Spore. Especially when he knew they were in a nest that was formerly a nest of creatures the species he was playing had cleared out. Although he has now learned through lurking on the Spore.com forums that they're just loading screens (for want of a better wording) their sheer resemblance to the {{Film/Alien}} eggs creeps him out and instinctively keep his critters away (the fact his ideal Spore species he wants to play out is an omnivorous but cute little guys but who turn out to be absolute bastards in Tribal stage onward to Space basically speaking...it's jarring seeing cute little things then seeing the Gigeresque cocoons...)

Oh my Spode, I'm not the only one!

It gets worse. Try using the intimidating roar or the siren song abilities next to the cocoons. The visuals for creature reactions can be seen eminating from within the cocoons. The creatures in those cocoons aren't sleeping, or hibernating. They're fully awake and aware. Sweet Dreams.

One time while shopping at Cosco, this troper's mom found packages of fresh tuna sold for very cheap prices. The price of fresh tuna has skyrocketed and continued rising these last few years, so she assumed it must have been mislabeled. Now she regrets not getting more.

A horrible, horrible subversion: The FinalFantasyVI "invisible sketch" bug. "I've got all this equipment, ''and'' spells I would never normally use? Awesome! I can't finish the battle? That's too bad. My game's been deleted? Oh, fuck! Fucking fuck on a fucking stick! Fuck, man, fuck!"

This is likely rare to happen, but in Dead Rising 2, under some circumstances, your weapon might not break when it's meant to. This troper came across this with the vaccum cleaner/saw blade weapon which didn't break when it was meant to (I believe I was hit around the same time I got it's final use in), and this as such resulted in leaving with with a weapon that gave me 125PP (I didn't have the proper card, only the scratch card) per kill, killed all zombies in one hit, and leaving me largely invincible (the only times I dropped it was in the outside area the snipers reside). Came in rather useful as this pratically left me as a one-man army and helpd me score a 1000+ body count in one multiplayer sitting. My friend was just like "IT STILL HASN'T BROKEN?!" the whole time!

This troper has had several weird happenings from the Glitch Gremlin:

First time I beat ''KingdomHearts358Over2Days'', Riku begun to attack the wall for some reason. I've ''never'' gotten him to do that again.

In ''GuildWars Prophecies'', some glitch sent me from a mission where I was gathering Chosen for the White Mantle (I forget which one) to Aurora Glade. So imagine my confusion when all of a sudden, I was ''fighting'' the White Mantle when the previous cutscene I saw had shown the ''Shining Blade'' as the enemy - so I was like, "...what the hell?"

''{{Bully}}'' gave me ''so'' much fun. There was one time where I saw someone stuck in the stairs, and the prefect once went after me and got stuck in the wall. Then in another mission, I was trailing Lola and a prep she was dating...and a car ran over the prep. There was also one time where I managed to knock out Algie with an egg - and this was in ''one hit'', too.

One fun glitch in ''TheSims''. I was ignoring all my neighbours, and then suddenly, I got a message that someone had died - and they weren't in my family. I found where they were and there were literally ''four neighbours'' who were standing on the edge of my property after having rang the doorbell several days ago yelling for food. They literally just ''stood there'' until they died.

Another silly glitch in ''PhantasyStarIII'', Ayn hit someone for a thousand damage with a physical attack. I've never been able to replicate that.

(same troper) During my playthrough of Pokemon Heart Gold, for some reason, my Typhlosion (With Pokerus) gained 22 defense on a level up after I beat Jasmine. The Effort Values seemed to have infected all of my pokemon, since my scizor and Nidoking gained over 10 defense on a level up.

Whilst doing some personal programming for a project and adding a fancy fadeout effect for a enemy, this troper had accidentally set the enemy to create a new instance of itself and teleport somewhere else in the map instead of creating the fancy fade effect of itself and teleporting somewhere else. Cue this troper flooding a room full of the accidental replicating enemies then trying to kill them all.

This troper got to the last secret in ''TombRaider III'''s Lud's Gate stage by stealth-killing the guard that alerts the frogman who closes the secret, causing the frogman to glitch up and freeze in place, although you die if you touch him.

I was playing A Crack in Time, when one of the late-game FMVs (involving six minutes worth of time travel) decided to play twice. Wut. It was rather confusing when it happened, but afterwards the controls were locked until Ratchet died.

Funny you should mention that game. I had a similar event near the end when I died while chasing Azimuth and suddenly returned to the start as Ratchet, with two ships and no where to go. Freaked me out a bit before I got everything back to normal. I think it was caused by trying to warp to the very last level and then leaving it the same way.

I had an ''awesome'' experience with MineCraft, although it wasn't the source of the bug. See, my computer's graphics card was screwing up, and it changed certain shades of color. One of these changes was from black to green. It was annoying at first, but then I realized that it basically gave me ''night vision'' in Minecraft.

I was playing LegoStarWars just for kicks, when I crashed into something on a speeder and died just as a cutscene started. Then when the cutscene ended, I had no health. I could walk around with ''no health'' and shoot people. I was entirely invincible, too–when I got hit the shots just bounced off. Sadly, it ended when I hit a vehicle.

I had started a playthrough of ''Link's Awakening'', in which I started off by going to the doghouse world, grabbing the Magic Rod, and playing through the entire game with it. I really like it, though I've noticed pretty much everything in the game is immune to it for some reason.

Also, I managed to get five aces to appear in one game of Solitaire.

Me again; I've noticed that if I hit right mouse while reloading the SPAS-12 in ''Bad Company 2'', my character will load 8 new shells, regardless of how many were still in the gun. Also, a friend of mine has discovered how to combine water and lightning elements in ''{{Magicka}}'' (the two normally cancel each other out).

I once played ''Sven Coop'' with my brother right after installing, without restarting as the installer suggested. For that one game only, I was able to use the armor-powered electric crowbar.

Me in Minecraft, I have this blackout crash glitch of unknown causes (PLEASE TELL ME HOW TO FIX), but this glitch causes You're inventory to save but not the enviroment (including chests), this caused it to clone a fresh diamond pickaxe, a half-durability diamond shovel, and a (Near) fresh diamond sword, along with several dyes. What is frustrating is that it happened a day before and made Me LOSE some of My tools of value, That would be a legit reason to use invedit.

My brother was playing {{Dead Space}} 2 and Isaac became a pair of dis-embodied legs, I saw this while talking to someone and how She was un-phased by Isaacs "Exotic" form, then it became a pair of legs and a floating empty helmet.

This troper thinks that the ''WheelOfFortune'' game on {{Facebook}} has an incredibly helpful bug. In literally thousands of spins, I have only hit Bankrupt twice. Either I'm insanely lucky, or the Wheel is programmed strangely, or both.

Time for the rare non-game example. Troper went to summer camp at a local museum of science in middle school. There were several computers available that were used to display specific movies and websites. So, naturally, this troper learns that by repeatedly opening and closing files, it is possible to force the program to close, providing easy access to sites like Newgrounds.com. He decided to show it to his peers in order to distract them from possibly being bullies. Summer campers take advantage of that bug to this day.
