"The Aristocrats"
A fairly funny documentary about a bunch of comedians who tell their own twisted versions of a VERY dirty old joke. I won't give away the gist of the story, but let's just say it involves incest, bestiality and various scatological preoccupations (depending on the version told)!. Working 'blue' to the point of taboo, the best schtick in the flick comes from the hilarious Sarah Silverman, the 'South Park' kids, and from -gasp- Gilbert Gottfried! Grade=B+
