There's usually nothing in a guy's joke in which we have to understand what's going on in someone else's mind.

When you look back at the older cartoons, they're very much more observational cartoons. And the cartoon, the people in the cartoons are not making the joke.

I've learned not to look a gift horse in the mouth. Why you would want to look any horse the mouth considering how infrequently they brush is beyond me.

I think The New Yorker's cartoons aren't very political because the people who do the cartoons aren't awfully political people, and they aren't paid to be political. I think editorial cartoonists are. That's what they do. They probably have a great natural interest in politics, and then they are paid to do it, so they sort of have to hunt out these ideas. I admire editorial cartoons, but I'm also sort of happy that I don't do them because I'd hate to have to label things and I'd especially hate, more than anything, to label something Dennis Hastert or Mark Foley.

I'm really interested in the link between creativity and humor because humor is a type of creativity, and I do think that humorous people and humorous health helps creativity.

Humor of all types is notoriously subjective. That's true not only between different people but even within an individual at different times. This subjectivity is often masked when your in a group because laughter is contagious.

The most popular cartoon of mine is a guy on the phone looking at his appointment book and saying "No, Thursday's out. How about never, is never good for you?"
