I did stand-up comedy for 18 years. Ten of those years were spent learning, four years were spent refining, and four years were spent in wild success. I was seeking comic originality, and fame fell on me as a byproduct. The course was more plodding than heroic.

I knew I wanted to be in show business so I took the path of least resistance. I loved comedy. But you never know you are funny until people laugh. It's just what I was interested in. I could make people laugh, I guess, but doing it at school and doing it onstage are very different things.

I'm for the Wall Street Occupiers. But will they accept me when they find out I sell packaged mortgage default instruments to children?

The banjo is such a happy instrument--you can't play a sad song on the banjo - it always comes out so cheerful.

Teaching is, after all, a form of show business.

I thought if I had a Twitter feed and say I had a following of a 100,000, that means 100,000 of them would be interested in my book. It was logical, but it didn't turn out to be true. It turned out if I had a Twitter feed of a 100,000, four of them were interested in my book.

I knew I wanted to be in comedy but the path of least resistance was doing stand-up in folk music clubs where I could get on stage. I guess you could get up no matter how bad you were and you didn't have to audition. You just got up. Everything else required an audition and if you auditioned for a TV show, you would stand in line with a hundred other people. But at the clubs, it was okay just to get up, so that's why I started in stand-up.
