I just had a son and had to take him to the paediatrician and he measured his head and apparently he's in a group in which only 14 per cent of the population have a bigger head than him. Then she said: "Do you mind if I measure your head?" I said: "Go ahead." And she was shocked, because less than one per cent of the world's population has a bigger head than mine. So I guess that means I'm pretty full of myself. Or that I have a huge brain.

I recommend that everyone in their youth be as out of shape as possible so that when you turn 40, people can go, "Wow, you look much better now."

With the acting, it's somebody else's brainchild, and I'm just sort of helping flesh it out. There's a special satisfaction to being the brains behind the operation.

Tenacious D loves Auntie Em's. Her delicious nutrients are always energizing and indie-fresh. Where does she find those unbelievable recipes? Somewhere over the rainbow?

The movie Spinal Tap rocked my world. It's for rock what The Sound of Music was for hills. They really nailed how dumb rock can be.

When I was in High School I fell for pretty much any girl I ever met. But I was so desperate that I couldn't get any of them because they sensed my desperation! After many, many years, I learned to relax and just be myself.

I seem like a big bombastic outgoing dude, when it comes down to it with the ladies, when I was a single, free-wheeling dude, I was always very shy. It was difficult to form sentences with the girl of my dreams.
