Posting for Feynman recognition. My favorite of his material is on "Cargo Cult Science".
"One time I sat down in a bath where there was a beautiful girl sitting
with a guy who didn't seem to know her. Right away I began thinking, "Gee!
How am I gonna get started talking to this beautiful nude babe?"
I'm trying to figure out what to say, when the guy says to her, "I'm,
uh, studying massage. Could I practice on you?"
"Sure," she says. They get out of the bath and she lies down on a
massage table nearby.
I think to myself, "What a nifty line! I can never think of anything
like that!" He starts to rub her big toe. "I think I feel it," he says. "I
feel a kind of dent -- is that the pituitary?"
I blurt out, "You're a helluva long way from the pituitary, man!"
They looked at me, horrified -- I had blown my cover -- and said, "It's
reflexology!"
I quickly closed my eyes and appeared to be meditating."
