The core of Animal House was about prejudice, about equality, and about inclusion/exclusion. It was about a group of people who were together and anything went. Anybody who wanted in could get it in. Then there was that other group that nobody could get in, unless they were white, and just alike. It was very representative of the culture in the '60s, '50s, and '40s in America.

I was just dying to get out of the constraints of television, and the constraints of the parts I'd been playing. I had taken a bunch of improv classes and was performing with The Groundlings. I wanted to get into more adult, risky stuff.

I had read the Animal House script, and by hook and crook, I finally got an audition. It was a great one. John Landis followed me out into the hallway afterward and said, "I've never done this before, but you've got the job. Now don't tell anyone!" I've never had a director do that. It was one of those Hollywood-dream-come-true stories. They saw me as a surfer or cowboy, not a preppie, but someone begged and borrowed me an audition, and I went in and got it.

The funny thing about The West Wing is - and I don't know what Aaron Sorkin says about it - but I'm convinced it was a comedy. It's a very intellectual and cerebral comedy, but it was SportsNight in the White House. It had an energy and a vitality and an intelligence and a passion that's rare. And it was extremely difficult to do, because they were so demanding about the dialogue.

Sam Kinison was one of the most compulsive people I'd ever seen. James Belushi was that way, and Chris Farley was that way. He was incredibly talented and made me laugh so hard, and there was nothing he wouldn't say. Such a unique, amazing, cynical, realistic, but still optimistic look at life he had. It was great fun to get to know him.

I used to take acting so seriously, but after we did the Quest pilot and the show sold, Kurt Russel said, "You know, you work too hard. You'll make yourself sick. You can't work that hard doing a series, because it goes on so long. It's like a baseball season. You've got 162 games. You can't just go all-out the first week or two. You can't maintain that pace." And it's true.

I worked with some of the best actors I've ever worked with: Mel Blanc and Don Messick. They could play a scene against themselves. Think of the characters that Mel created, and they're as good or better than any performance anyone has ever given. I mean: Daffy Duck! Think of the specific voice Mel gave Daffy Duck or Bugs Bunny or Porky Pig... It's just astonishing.
