World's Filthiest Joke

Link via Taunting Happy Fun Ball:

Some of the biggest stars in world comedy have worked together to put the world's filthiest joke to film. The joke, known as the "Aristocrats" is one of the longest running in-jokes in the standup comedy industry, being passed amoungst comedians backstage for years. The joke, which is not really funny (which is part of the joke - you see), is about a family auditioning for a talent show using the most obscene behaviour possible.

Eddie Izzard, Billy Connolly, Chris Rock, Robin Williams and the makers of South Park are among the comedians who have recorded versions of the joke for the film which is to be shown at the Edinburgh Fringe later this year.

Here's the Southpark version, which is said to not even be among the top 5 dirtiest.
