I've made a career out of playing the id: the guy that says whatever pops into his head.

I thought I would be a teacher; I think my eventual goal was to be the principal of my old high school.

I think there's this new kind of character; it's a sidekick-slash-leading man role. People like Zach Galifianakis and Seth Rogen have been really successful in those roles. You don't have to be this square-jawed, chiseled, deep-voiced Superman; you can be funny and normal and put in the leading man category.

I spend a lot of time on TV doing the same sort of thing. I found a niche in TV where people are willing to steadily employ me to do this one thing, which I put spins on and change.
