This isn't really funny/crazy, but I never really had any... absurd storylines. On GJ, I was part of this one storyline where I was playing a down-and-out journalist interviewing a Southern beauty queen on her recent pageant win. While they were doing the interview (a walk and talk one, since my character wasn't really paying much attention and would eventually just bs the article.) they were attacked and kidnapped by her jealous ex-lover. It was so intense and (in a way) absolutely nuts. They were holed up in this old hotel, and he was force at gunpoint to, uh, have his way with her.
HECK YES. IT WAS AMAZING.
I wish I had crazy stories, though. :( My RP life is insanely boring and plain.
