The one thing you don't want to do is say, "I'm going to be different than anyone else — I'm wearing jeans!"...Steve Martin told me when he started out he was dressed as a hippie, and that shocked me. He was like, "Well, I was doing avant-garde stuff. Then suddenly I realized avant-garde comes out better from a guy in a white suit." I thought that's pretty fucking smart.
People laugh at odd combos. High-low, skinny-fat, smart-dumb. Comedy is in the contrast.
