Laughter is binary: It either happens or it doesn't. As each joke arrives in the course of a film, the cavernous space of the theater is either filled with joy and laughter or with the quiet of cringing embarrassment. Every time you step to the plate to make a joke, you're going to experience one or the other.

Comedy, when it works, is light on its feet and has the illusion of complete spontaneity: as if there is no film, no camera. You are standing there experiencing it all in real time. This illusion, I believe, is why so many people think comedy is easy.
