Crispin: I think humor delineates who your friends really are. I worked on Little Noises (1992) with Rik Mayall, and he described to me a theory of humor. With pack animals, if there's a sick one in the bunch, the others will growl at it and try to get rid of it. This translates to the comedian on-stage. There are two types of comedians. One who says, "Everybody laugh at that person," and the braver comedian who makes them laugh or growl at himself. It brings people together. The audience laughs at this sick thing: they become a part of this clan or tribe. And that's where you get your friends: you share a certain humor about the sick and the foolish.
