The funniest one I remember hearing that was done at my school was about pigs. Someone had gotten three pigs, painted them with a red 1, 2, and a 4. And greased them *really* well. They left a note in the main office on the door saying they had released four pigs in the school. They spent all day trying to catch the buggers. And of course, there was only THREE pigs lol.
What I've learned from living in this country : America is a bad word, so is Religion.
