I've had so many hot, cheesy, corny loves of music in my life. I had a very intense Billy Joel period. So once you've really Joeled it up - there's some good periods of Joel; it's not all hot cheese. But I can't judge anyone else for their cheese. I've deep-sea dived in the Gouda.

I serve society by rocking!

When I was a kid, I thought I was the strongest man in the world. Then, the fastest runner and then the smartest person in the world. One by one my delusions got shut down. Now I just see myself as the lamest guy in the world.

Every movie presents its challenges.

I took a year of karate. It was like obligatory... every kid was taking like one year of karate and one year of piano in my town. It was Bruce Lee and Liberace. But I was not a white belt. I graduated. I had a colour belt - but that's all you need to know. It could have been black, it could have been yellow, or it could have been anything in between.

I just remember the early days of Tenacious D. There was no talk or thought about doing a TV show or a movie.

Part of the acting gig is when you're let loose some improvs and put stuff into your own words every once in a while. That doesn't get you a writing credit or more money. It just makes it more fun.
