Well, anybody can be a straight man if he hears well. You just have to wait for laughs. A straight man just repeats the questions and the comedian gets the laughs and you just wait for them and don't let them die completely at the tail end of the laugh.
George BurnsI use the cigar for timing purposes. If I tell a joke, I smoke as long as they laugh and when they stop laughing I take the cigar out of my mouth and start my next joke.
