If you understand comedy, you understand life. Drama, death, tragedy – everybody has these. But with humour you've got all these, and the antidote. You have found the answer. It doesn't follow that because you are a good comedy writer, you're a happy fellow. I've got one of the most miserable faces in the world. I am only happy when I am working. If I'm not working, I get screwed up because my time is going, my life is slipping by.
