I watched the Jerk again a few weeks ago and was laughing out loud at many of the scenes. My favorite is when the motorcycle stunt driver is feeling Steve Martin's butt, and his job is guessing weights at the carnival. His response, "You're really trying to be accurate."
The joke with Chappelle is black folk drink lots of Kool-Aid and eschew healthier food options. He's done some funny bits on other food stereotypes too, like chicken and watermelon.
So who you voting for, sloop?
I'm going B by the way. A spreads its 'joke' too thinly: I've never seen The Jerk, but the physical comedy is excellent in this clip.
