Appearantly there is a joke that comiedians tell each other. The joke starts with the same set up and ends with the same punch line, but each comic improvs the middle. And the idea is to be as dirty, gross, and controversial as possible.
Penn Jillette of Penn and Teller fame has produced a movie opening this weekend called “The Aristocrats“. It is a collection of comedians doing the joke. The link above has a great story both about Penn and the movie.
Reminded me that when I’m in Vegas in October I’d love to see their show, but alas they aren’t performing while I’m there.
