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.

We're in the dark ages if J-Lo can have a music career because of her ass. And let's face it, that's it.

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.

Just because you don't know how to do stand-up doesn't mean you don't know how to put on a show.

I always feel bad for people getting married and spending upwards of a hundred thousand dollars. It just seems so absurd to me.
