Two unscientific responses:
(1) As long as we’re quoting fiction, here’s some closely paraphrased dialogue from The Waterdance (with a great performance by Wesley Snipes as Raymond):
Scene: Group therapy for recent paraplegics.
COUNSELOR (white man, also in a wheelchair): Oral sex comes in handy.
RAYMOND (muttering and shaking his head): Aw, there ain’t gonna be none of that, now.
COUNSELOR: Did you say something, Raymond?
RAYMOND: Look Doc, I don’t mean no disrespect, but a woman was made to service a man. That’s just a biological fact.
COUNSELOR: I think some of us here might disagree with you.
RAYMOND: You’re telling me you want me to eat some pussy. (emphatically) Black men don’t eat pussy!
BLACK MAN WITH DEEP VOICE AND JAMAICAN ACCENT: What you gonna do, Raymond, use a straw? (everyone chuckles)
RAYMOND: Maybe I’ll use your big nappy head!
COUNSELOR: Raymond, it’s your choice, but I’ll tell you – I’ve been in this chair 18 years . . .
RAYMOND: Oh, and you’re telling me that you go down on a woman?
COUNSELOR (smiles): Every chance I get.
RAYMOND: Aw, that’s disgusting. That’s just absolutely disgusting.
(2) A story I’ve heard a few times: Once Billy Joel and a friend were backstage at a Paul McCartney concert, and were looking for something to eat that wasn’t vegetarian. They asked Paul if there wasn’t any food around that had meat in it. Paul replied, “Come on, guys, you know I don’t eat anything that has a face.”
Billy’s friend said, “Poor Linda.”
