This troper. Constantly. Late to class? "I was having a party selling drugs to a friend to help her detox from hydro. And then I punched a kid in the face. Of course that's why I'm late, it's legit." Got away with it.

In her earlier years, this troper had some trouble with shoplifting. If someone asked how much something cost, the answer was "I dunno, I stole it." However, the best moment was when this troper actually somehow managed to steal alcohol (not recommended kids. Stealing is bad.) She got a call from her mom right after, asking what she was doing. The answer? "I just robbed a liquor store. I'm drinking some vodka, want some?" She got away with it, and regretted it ever since.

ThisTroper doesn't actually use it to cover up misdeeds, but regularly tells facts about his life with enough outlandish detail that he knows no one will believe them, leaving people with the impression that he's much, much more normal than he actually is. He's told a few people that they don't really know him until they've realized how rarely he's joking.

I've introduced a friend (and fellow Troper) to the ''DresdenFiles'' series. He'd been joking while reading ''Fool Moon'' that Harry was clearly going to die, so when he got to book 3 (''Grave Peril''), I told him "Oh, yeah, Harry dies in this one." He didn't believe me- it helps that I have a habit of false spoilers (although they usually involve at least one of gribbly green aliens with tentacles and ninja, whichever is least likely to actually happen in the work). He's finished it now, but I have yet to see his reaction to the bit where Harry temporarily dies so he can team up with his ghost...

I personally had a lot of trouble with this because the actual confessions I made people thought were BS but the sarcastic ones were taken seriously. Obviously, I must be doing something wrong here...

I'm the flip side; I mistake actual confessions for BS and take sarcastic ones seriously. Once, a guy even confessed to me that he wanted us to be more than friends, and somehow I mistook it for a joke.

When I was in middle school, we had a saying: 50% of what you joke about is actually the truth. It was a great comeback when people responded to your insult with sarcarsm. "You're stupid!" "Oh yeah, I totally am." "You know, 50% of what you joke about is true..." These days, though, probably 90% of the things I say in a sarcastic tone is actually true.

Physicist and prankster Richard Feynman did this at MIT; see Who Stole the Door in ''Surely You're Joking, Mr. Feynman''.

I have seen at least three people use this successfully, including one time a friend, when asked what we were doing on a school computer, replied that we were play extremely violent, stolen games. The aide returned to their work, and we returned to the pirated copy of {{Starcraft}}...

This Troper's sister has a habit of delivering everything in total deadpan, so for most people it's difficult to tell when she's joking and when she isn't. However, she is indeed partial to sarcastic confessions, which led to a small mental breakdown on the part of our overly-stressed mother when an actual use of sarcasm was misidentified as the truth. Sister has toned down her use of sarcastic confession considerably since.

This Troper's gossip-insane friend informed a girl that I was attracted to her. I proceeded to respond "True story, I'm actually really attracted to you." in a casual voice, getting a laugh, then I told her "I also have a knack for saying true things in a sarcastic voice."

One of This Troper's roleplaying characters used this to dodge an inconvenient question. Every word she said was true. #QUOTE#'''Character:''' OK, ''fine''. I'm secretly seeing Trevor behind Claud's back, and we're going out tomorrow night and I'll probably let him touch my tits. Also, I'm still a virgin, and I'm really Charlotte Bronson's mind in Eleanor's body after Von Krankenstein switched our brains. The ''real'' Eleanor is at Charlotte's house fucking the nerd's lesbian girlfriend.

This troper had a conversation with a coworker in which she said, "Take your time packing up, I'm going to run to the grocery store and grab some batteries." "Batteries, huh? For your vibrator?" "Yes, Coworker. For my enormous blue multipronged ''vibrator'' *eyeroll*." His shot in the dark had hit uncomfortably close.

I'm working on a story. Towards the end, Annabelle is at school after suffering some major injuries. She and Daniel are walking down the hall when TheLibby approaches them. #QUOTE# TheLibby : Hey, how'd you break your leg. #QUOTE# Annabelle: Oh, see this evil vampire attacked me and nearly killed me, but Daniel, who's also a vampire, saved me. #QUOTE# TheLibby : If you didn't want to tell me the real reason, then you should have just said so.

I did tell him my true feelings eventually though.

When our boss asked me and my co-workers why we were behind on the project, I said that the data we needed had not been transmitted for several months (true) so we'd been building a massive subterranean railway instead. He laughed at this absurdity, especially since we ''had'' managed to do other look-busy projects during that time. I nearly got ''strangled'' by my co-workers when he left, but it was worth it.

Why thank you, good Sir!
