Okay, so you know going into it that it's a movie about the filthiest joke in the world. They're not kidding, so don't think it's movie hype.

So, if you can deal with hearing "the filthiest joke in the world" in its countless permutations, you will also experience some laugh-out-loud moments.

You actually hear the joke early on in the documentary, so it's not exactly a "spoiler." The funny part is all these comedians going on about it, and doing their own version.

A guy goes in to see a talent agent. He says, "I have a great act - I do it with my wife, two kids and our dog."

Agent says, "What do you do"

Then the teller inserts whatever foul, scatological, incestuous, bestial things he dares. Believe me, these people dare a LOT!

The agent says, "Wow, that's quite an act! What do you call it?"

The Aristocrats!

You could substitute The Sophisticates, or whatever incongruous name you like.
