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.

I think Nixon says a lot about those times. It was possibly hard, in the '90s and early 2000s to understand the grip of fear that communism had on the country in the 1950s and 1960s - a fear Nixon rode like a endless great wave on the Pacific to high office. I'm sure, though there's no evidence of it, one of the things that rankled him down deep was that it was called McCarthyism and not Nixonism.

When I was growing up, we learned our history almost as lives of the saints. And it came as a shock, "Oh, Jefferson had slaves?" It always comes as a shock to us that elevation to the White House didn't somehow cleanse them of all their deep character flaws.

When it moved to Friday night it disappeared, when they find another show that can do what The Simpsons does, they will be delighted to do cancel The Simpsons.

I just think everyone knows you go on those [political satire] shows if you're a politician to, "humanize yourself" - to show, "Hey, I can take a joke." Well, why should satire be in the service of humanizing these people who are supposed to be the target of our venom and vitriol? I think that's unseemly.

The Simpsons will end as soon as Fox is able to find an 8 p.m. comedy hit to replace it - so I give us another 50 years.

I always used to sit next to Mel Blanc when we'd do the shows. When you have Jack Benny on one side and Mel Blanc on the other, you're not going to go far wrong.
