I was never into candy and games and clowns.

The first thing you've got to do is know your craft, and then you can do something else with it.

There were really funny characteristics about this guy [Richard Nixon], chief of which would be that he seemed to devote about 85 percent of his waking energy to suppressing any sign of his emotional response to anything that was going on around him, and the other 15 percent blurting out those authentic responses in the silliest and most inopportune ways. And he had these smiles that would come at the most inappropriate times - just flashes that there was an inner life screaming to get out.

I happened upon a memoir by a midlevel White House staffer, and he had been in the room that [Nixon's last] night [in office]. This guy's memoir told me what Nixon's last words were. And they were, on August 8, 1974, to the crew: "Have a Merry Christmas, fellas!" That was just so bizarre.

Satire is an art best practiced behind the back of the intended target. I think inviting politicians on a satirical show becomes a very big trap. Because one of two things happen: Either you have to kind of unsharpen your fangs because you can't be quite as cruel to people to their face as you are behind their backs... Or you don't defang, and those guests get the word and they stop coming.

[C. Montgomery] Burns is much purer evil than Nixon was. I think it's the purity of his evil that attracts me as a comic character.

Sometimes, songs spill out of you very fast, and sometimes you have to wrangle them to the floor. But the same thing is true of comedy, where sometimes it really flows.
