I paint digitally now. A pity, in some ways, as the biggest price one pays is that you no longer have a finished piece of physical art to hang on a wall. I miss that terribly.

Cartooning is about deconstruction: you gotta tear something down to make a joke.

I'd be a Libertarian, if they weren't all a bunch of tax-dodging professional whiners.

The cartooning was always just an abstraction. It was an income. It was making me famous. It was allowing me to go and do other things that I'd wanted to do.

I drew the last image ever of Opus at midnight while Puccini was playing and I got rather stupid. Thirty years. A bit like saying goodbye to a child - which is ironic because I was never, never sentimental about him as many of his fans were.

My post-child period resulted in one instant change: I write shorter books for kids.

I'll confess right here that I secretly wish I'd have drawn a strip about a little boy with a fake tiger, going for adventures throughout the universe in spaceships of his imagination.
