Totally awesome pranks?
I have a friend who says he is the master of all the jokes, his sister is my best friend and wants to demonstrate its wrong. We have a pretty good opportunity and I and his family are traveling from Michigan to New York next week. We stayed in a hotel for about five days. I have no idea what to do with it. But me and my friend who want to return. They have to be careful though, he has a nasty temper. Any ideas?
