Penn Jillette (of Penn & Teller fame) invites nearly 100 famous superstar comedians, like Whoopi Goldberg, George Carlin, Drew Carey and many more, to come together to share the joke known as "The Aristocrats," which as a rule, is only told to each other. It is considered by many to be the world's dirtiest joke and it is accompanied by a burlesque routine too bold to be performed in public. 2005/color/86 min/NR/fullscreen.
