Well if you think about it most private schoolers (or at least enough to make it hell) were once public schoolers who were sent there because:
They were punks and their parents sent them there to straighten the kid up, the kid was an idiot and got expelled from the schools of his area or is just a complete snob
I go to a private school but have never heard of any nipple shenanigans. For the guys at my school these are the things they would do: super glue coins to urinals or any other spots,wad up paper towel and throw it on the ceiling (It sticks and eventually will fall onto an unsuspecting victim) openly leave in the middle of class to masturbate, and write things using permanent marker on the walls like "i dominate the pussy". Probably much worse things, but that's all I heard about from the behavior meetings we have. I can say us private schoolers quite fucked up in the ole noggin.
Nah mate, my school (an all girls, CATHOLIC, private school) used to put clear gladwrap across the toilet seats, so when people pissed, they pissed all over themselves. Ah, the memories *wipes away tear*
