Snowball throwing was banned because a nephew of a friend of a friend of a teacher was supposedly blinded by one. Same school had an assembly that informed us that listening to heavy metal would make us want to kill our friends.

FWIW, this can actually happen, although I still think that's an overbearing rule. One of my younger siblings had a teacher who was blind in one eye - ice shards from a snowball when she was in elementary.
