So South Park’s creators made their version of the Aristocrats joke. I have to say, it’s pretty good, but it’s nothing to Bob Saget’s. That man has a filthy, filthy mind. Bless his rotten little heart.
For more about the origins of the joke, not to mention Bob Saget’s and many, many other people’s versions of the joke, go see this movie. It’s awesome, and it’s the only documentary I know of about a joke, and not an individual comedian.
