Usually when I sat down to draw a cartoon, it would be more of a reflection of things in my past. Or it could be something I had experienced that morning, or that week, or something I might know that's part of my background.

I don't know where my ideas come from. I will admit, however, that one key ingredient is caffeine. I get a couple cups of coffee into me and weird things just start to happen.

You always hear a headline like this, 'Man Killed By Shark', you never hear it from the other perspective, 'Man Swims in Shark Infested Waters, Forgets He's Shark Food'.

I thought some of my earlier cartoons were not exactly great shakes at the time I drew them. Now I see a certain innocence in them. The humor has a kind of purity to it, I guess. And it works better on some level for me now.

The problem, Mr. Fudd, is that you've been having a sublimal effect on everyone in the factory. We're proud of our product, Mr. Fudd, and there's no company in the world that build a finer skwoo dwivuh. ... Dang! Now you got me doing it!

I never liked my own species. On why so many of his comics are about animals, in an interview.

The idea for any cartoon (my experience, anyway) is rarely spontaneous. Good ideas usually evolve out of pretty lame ones, and vice versa.
