Whats the worst thing you've been in trouble for?

The worst thing i’ve done and been caught for I would have to say was bringing a switchblade to school and giving it to another student. It was a safe situation and nobody was going to get hurt, so it was all in “goog” intention, BUT somebody saw the transaction and reported it to the office. I got suspended, because I’m a good lier ;]
But I still admit… I’m a fucking dumbass, and deserved it. But later I was “associated” with some kids who accidently light part of the school on fire with a smokebomb. Since I was the one who actually bought it, I got most of the blame and was expelled. I then later appealed to the school district and talked my way back into the school.
But enough about me, what happened to you guys? :D
