The Boogeyman is your conscience. The Boogeyman is the result of your own bad behavior. I love this Boogeyman.

A comic book is the opposite of a cartoon. In a cartoon, you want to simplify the idea, so when they look at it at a glance, they get it. Boom. Simple. Direct to the point. But when you're drawing Groo, now it's a narrative, a story. You want the viewer to get involved in the story. You want him to feel like he's in the town to follow your main character. So I love to add lots and lots of things in it. Things that people will enjoy going back to and say, "Oh yeah, that's how a market must have looked in this fantasy world, with people selling meat here and dishes here."

When sadness happens in the middle of work, I separate my personal grief from my train of thought.

If the gag is complicated, you spend more time thinking about the way you’re drawing it.

When I'm drawing a bottle or a town or a market, I transport myself there. So I start drawing everything that I'm looking at while I'm there. Here's a guy selling the meat, and he will have a hook, and you start adding things, and it's a lot of fun.

If I see that something is wrong, I don't care who says it. Whether it's a Republican or Democrat, the left or the right. If they are on the opinion of the right thing, that's what I will talk about. I won't proselytize or make the strong things to influence other people about any particular politics, except the decency of things, the logic of things. That's why I don't get that much involved in politics directly.

I'd love to do a whole series of stories and have them collected into books.
