The thing that was interesting to me about Relationshapes - as opposed to most of the other cartoons I've ever made - was I knew when one worked and when one didn't work, but I couldn't really explain it.

I'm interested in the structure of art and how it works. And the content is also interesting, but I don't want to keep the same structure and just plug in new content every week.

The thing I hear about a lot is when people over-sharpen their pencil with a single-blade pocket-sharpener and then when they put the pencil to the page, their tip breaks and pencil points always break irregularly. It always gets all jagged and you have to refresh the point. That's a common complaint.

I would make a comic for Rolling Stone every two weeks, because they're biweekly. And then I would make weekly comics for my weekly papers. It was on two parallel tracks. And then they all got collected in a book.

I don't think I would've ever dared dreaming of becoming a professional cartoonist. I wouldn't set myself up for that disappointment.

Everyone has pencils in their house, no matter how hip and contemporary they are.

I didn't dare to dream of making money. But now of course, I've made many thousands of dollars sharpening pencils.
