I've been doing Nixon pretty much my whole professional life. I was in this comedy group called the Credibility Gap in Los Angeles when he was president. I was doing Nixon on the radio, and when we did live shows I physicalized him - if that's a word - for the first time. And then I did a Nixon sketch on a very short-lived NBC show called Sunday Best.

Because I don't do stand-up, radio has always been my equivalent, a place to stay in connection with the public and force myself to write every week and come up with new characters. Plus it's a medium that – having grown up with it and putting myself to sleep with a radio under my pillow [as a kid] – I love. No matter what picture you want to create in the listener's mind, a few minutes of work gets it done.

You're not just looking for laughs, but you're trying to do the characters first, and then the laughs come afterwards.

Music often happens even faster than comedy in terms of the creation.

Here's a guy [Richard Nixon] who had no gift for small talk, never liked to be around strangers, was physically awkward, and he goes into the one business that calls for ease with strangers and a gift for small talk.

The hardest work most of us do is maintaining the appearance of normality.

As a kid, I really did want to hang out with the grownups, so it was hanging out with the hippest grownups in the world. This was the nicest bunch of people I've worked with in show business, with the exception of the people around 'A Mighty Wind.' It really was a wonderful eight years.
