The Aristocrats (2005)

Comedy veterans and co-creators Penn Jillette and Paul Provenza capitalize on their insider status and invite over 100 of their closest friends--who happen to be some of the biggest names in entertainment, from George Carlin, Whoopi Goldberg and Drew Carey to Gilbert Gottfried, Bob Saget, Paul Reiser and Sarah Silverman--to reminisce, analyze, deconstruct and deliver their own versions of the world's dirtiest joke, an old burlesque too extreme to be performed in public, called "The Aristocrats."
