I saw The Aristocrats at the Sundance Film Festival this year and have been ranting and raving about it since. The documentary has a very simple subject: one hundred superstar comedians tell the same very dirty joke, a joke which has only been shared privately by comics since Vaudeville. You'd probably think that watching comedians re-tell the same joke over and over could get boring. It doesn't. It's probably the funniest movie of the year. Apple now has the trailer online, and you should definitely check it out.
