yeah, the day before christmas my school had an official rock paper scissors tournament. you get a winner from each class, then all the winners from each class go to the gym and theres a whole ladder of every class winner. it was intense since my school is huge.
Its actually crazy, I read a book on it once. It was probably the most funny thing ive ever read: Describing common injuries in RPS play " Knuckle dusting: occurs when one player throws an overzealous rock and strkes the other players hand with his knuckles, this action can result in disqualification and can sometimes be cripling to a players game"
