One of the games they play with it is "Potato". This is played mostly by the guys. They sit in a circle (I've seen 9 boys in a circle) and play, and as they lose they put their hands in a pile. The winner gets to hit the pile of hands as hard as he can. They will play this for the entire break time (about 30 min) and by the end their hands are sore and red. Its really funny. They complain about it, but we have no sympathy for them.

I've decided I'm going to have my kids (if I ever have kids) rock paper scissors everything too. Who wants to ride in the front seat? Rock paper scissors it. Who wants the last piece of cake? Rock paper scissors. I don't see a down side to this.
