It's so much easier to write for an actor than for an imaginary character and then try to fit that character to an actor. It doesn't work very often in my experience.

The first joke I got on the air I remember clearly. Dennis McNicholas and Robert Carlock wrote a sketch where they were evacuating the Titanic, and the last two guys on the entire ship were the two black guys, Samuel L. Jackson and Tracy Morgan. So Will Ferrell was running back and forth, saying, "All first-class passengers get in the lifeboat. All second-class passengers and third-class passengers get in the lifeboat. Let's get all the animals in the lifeboat. Let's put all the empty luggage in the lifeboat."

The best shows are always the ones that are very, very low-concept and just about great characters.

In a weird way, it's not different from any other kind of joke-telling. You make those calculations about jokes about celebrities: is this a fair hit or not? The stakes were higher because the whole world was crumbling around us, but in terms of joke-telling, it's all about feel.

In high school, my friend and I discovered that your cable-access station had to let you do whatever you wanted - it was like the Wild West. We made a couple weird things, like a tribute to the Zucker brothers, where we had a panel discussion about the Naked Gun movies. We wrote a script and made jokes that I'm sure were terrible and showed clips of The Naked Gun without permission.

If the doors aren't open, just kick them in and keep walking.

A million years ago, when doing research about the world of municipal government, one thing that struck me is how often people's job titles changed - from one department to another, from the public to the private sector and back again. People move around a lot, everyone has her eye on some other, slightly better situation in some other corner of city hall. Plus governments are constantly shuffling and reorganizing and shuttering or condensing departments - they are often byzantine hodge-podges of fractured org charts lying atop a bed of shifting sand.
