I think a play can do almost anything, because it's also a static form, much more so than in a movie. In a movie you can move the scenery, you can do anything any way. A cartoon, happens in a limited amount of space and a limited amount of time, and you can only get so many words before the reader's gonna get impatient. All of these forms that I enjoy are in a sense a slight of hand, where you have to suggest much more than you really show. You have to, in a sense, seduce the reader and trick the reader or the audience into going with you.

There's the excitement of adding color, which I didn't know anything about until 1997 or so, when I did my first picture book. So, the kid's book in particular have been exciting for me because it forced me to go back to the work I loved as a young boy reading Sunday's supplements and comics in the Sunday papers when I was six, seven, eight, nine. And number of which have been in wonderful collections, beautifully reproduced.

I told the doctor I was overtired, anxiety-ridden, compulsively active, constantly depressed, with recurring fits of paranoia. Turns out I'm normal.

That was exciting to be able to comment on civil rights. I mean, the civil rights movement that young people don't know about today, but Martin Luther King was considered by the establishment press in the early years of the sit-in movement as a dangerous man, and he was the equivalent at that time as Malcolm X. And he was told to stop his demonstrations; they were against the law and all of that. Now that he's sainted and sanctified we've forgotten.

When I am working a book, I go through my library and take a look through some of the great cartoonists of the past, like Cliff Sterrett, who did "Polly and Her Pals," or Winsor McCay who did "A Little Nemo in Slumberland," and Herriman - and I just looked through these guys and looked for somebody to steal. You know, looked for who I could swipe, or turn into - who's work I will turn into my work. And I still use, after all these years, these artists as inspirations. So, here in my eighties, I go back to when I was eight for my inspiration.

I learned to distrust writers who talked about how they squeezed the blood onto the typewriter. They just don't want you to know how much fun they have - you'll resent it.
