When my father died, my mother was still alive. And I think when your second parent dies, there is that shock: 'Oh man, I'm an orphan.' There's also this relief: It's done; it's finished; it's over.

I've done a lot of death cartoons - tombstones, Grim Reaper, illness, obituaries... I'm not great at analyzing things, but my guess is that maybe the only relief from the terror of being alive is jokes.

I think when your parents die, it is kind of like a moving sidewalk: you're not just on the sideline and watching them go by. You know, you're going to the same place they are.

I think I have a habit of, in my head, taking notes on whatever, you know, whether they're verbal or pictorial or just making a note of things as they're happening.

There's something about most phobias where there's a tiny, tiny corner where you think this really actually could happen.

My works were not - and they still aren't - single panel gags with a punch line underneath them. I like a lot of those cartoons; I just don't draw them.
