Jeffrey Ross discusses telling jokes and the film The Aristocrats.  A host of hilarious comedians give their own rendition of one of the filthiest jokes in comedy history. The joke has the same beginning and the same punchline at the end. Yet each comedian that tells it has their own variation on the middle. And that’s where the freedom (and generally the vulgarity) comes in. This was a crowd favorite at the 2005 Sundance Film Festival.
