There are just certain things you can't talk about with kids. I just totally do not believe in this sort of Bart Simpson character who infects so much of our literature and film and TV stuff nowadays, these know-it-all kids who seem to understand the hypocrisy of the adult world so thoroughly and can talk about it with such articulateness. That's bunk. Kids are kids; they're innocents, they really are. For a long time, no matter what they see, no matter what they're exposed to, they can't get it until they have developed enough.

You have to get through periods of being blocked. Everybody has them. For me, they have everything to do with self-doubt. It's never a matter of laziness or inability. It's just a matter of believing that what I'm doing is worthwhile, that it matters.I just make myself work. I just make myself go to work, whether I feel like it or not.

Russell Hoban created a tremendous marriage of characters and philosophy. The plots, the wind-up toy characters, the settings, they all work together to support basically a dark vision that the world is kind of a dump. And we all have to find our ways of surviving in it and of making it a better place. It's a world where we don't have much help, other than what we bring to the table. It's a world in which brotherly love counts more than anything else.

I found great value in teaching students from the outset of their studies how to draw very realistically. Otherwise, you're starting deep into the alphabet instead of having started at the start. If you discard essential things like drawing, design, color and so on at the beginning, then you're just sort of floating out in space, without any basis to work from.

By the time that book So You Want to Be President? came along, we had already had enough presidents that had shown us that presidents are human beings. So I felt I was contributing to the common knowledge there, but not revealing anything really new - sort of supporting what everybody already was suspicious of.

Even after the age of 50 it was impossible for me to see my mother as a human being. I felt she was a monster, and she had subtly been influencing my behavior and my thoughts and my dreams for so long that she was kind of a monster; she was a demon. And when I brought her back to life, I could feel that malevolent presence around me again, that woman who was totally incapable of giving nurturing to anybody, and, you know, her selfishness and her withdrawn indifference to everything but her own needs.

One of the glories of doing the book So You Want to Be President? was the shifts in tone, where I was able to be humorous and then very serious. And the impeachment page is certainly the best example of that. I didn't have to think too much about how to present this one. I got the idea right away that a good way of showing the shame of President Nixon would be to put him down in the shadows under the Lincoln Monument, with Lincoln sort of glaring down at him from an elevated, better-lit position.
