This will show my age but I got in trouble for the columbine shooting. Even though ti happened in a completely different state all the schools went into high alert. Since I looked like "that sort of kid" I would get searched by police if I even looked at someone funny.
I never actually got in trouble for something stupid, but I came close many times. Once for eating lunch in a stairwell right next to a door that led outside. Once for playing poker without gambling. Once for playing solitaire. Once for playing on a Nintendo DS.
Last time I was in trouble....I ran behind a door, friend pushed, I pushed back, door almost fell off the hinge. Or the time we played soccer in class, hit a lamp, the next day...it almost fell and crushed the teacher.
I once got sent out of the class and given a detention because some pretentious twats were playing some ridiculous game that involved punching and headbutting eachother until they bruised. For some reason one of them got quite cocky and boisterous and decided that I was part of the game, came over to me and started punching me. I dodged one of the punches and in doing so took one step out of the class room, and that's when I was penalised.
