I don't read cartoons because I think for the most part the comics don't have an interest for me. There's just nothing there these days that makes me want to go seek them out. I'm not trying to say my work wouldn't have sparked that same reaction from somebody else. There's just nothing there for me personally.

The message is not so much that the worms will inherit the Earth, but that all things play a role in nature, even the lowly worm.

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.

I think it's vital to be honest with yourself. You do have to satisfy yourself first. If you're drawing something, you have to ask yourself if it's something you genuinely think is funny. Or is it starting to fall into just a category, just kind of a shtick thing? I think it's important for all cartoonists to be honest with themselves about their own sense of humor and what they're doing.

It would be hard to get worse. I had only one direction to go.

I think I'm maintaining the quality, but internally I'm paying for it.

A long time ago, I became aware that many of us have a tendency to lump nature into simplistic categories, such as what we consider beautiful or ugly, important or unimportant. As human a thing as that is to do, I think it often leads us to misunderstand the respective roles of life forms and their interconnectedness.
