Oh, philosophy club sounds cool. Arguing about random Greek dudes' ideas? I'm in.
(Yes, I do know more about philosophy than that

and I would still be in.)
Calvinball is a sport in which there is only one rule: that the rules are never the same and always random. (It's from Calvin and Hobbes.) My siblings and I have a Calvinball team and we play against my neighbors.
My school had a mock trial but nobody wanted to do it

. Really sad. It kinda disbanded.
