I did some funny stuff in high school....lots of them stem from Biology/Chemistry/Physics where you can burn random things belonging to the foreign kids sitting near your lab station.
But the one that most disturbed me was in senior year my girlfriend (she went to an all girl Catholic school) did bad on a test and said we have to go back and change her answers. Around 10 or 11 that night we parked a block away, entered the building through one of those windows for rooms in the basement. Then there were gates locked all over so the only way to get to the room was to take some never used ghetto elevator for really old or handicapped people. All the while we had to duck and hide behind corners cause there were nuns walking around all over the fricking place. when we go to the room, she found something we moved by a window, I had to jump on it and climb up through a window that was 12 ft from the floor and let her in the room. She copied some smart girl's answers and we left the same way.
I didn't care as much cause at the time i figured not my school, what is the worst.....looking back, I guess jail is pretty bad.
