I did speak out about celebrities because I thought it was appalling. I thought that if the cartoon became popular, it was only going to last as long as the career of the people who are in it. They didn't make up timeless voices. They used their own. They brought nothing to the table, in other words. There was no alchemy. That's why a cartoon was so alluring, was that a human being went into a place and created this supernatural sound, or whatever sound it was supposed to be that was totally unlike their own, and did it in multiples.

John Kricfalusi is very talented; he used to really piss me off. But I did good work, you know? The Ren & Stimpy show without me was totally unsuccessful. So if there's anybody listening out there with any doubts about what I can do for a show: Try me. The thing is, I wasn't about to stop doing a job.

Robert Mitchum sounded different from John Wayne, and John Wayne sounded different from Clark Gable.

Even when I was coming through school I was a loner and I used to study music and listen to it and play it and play it, and I was in bands.

Tom Kenny is a master of changing a pubic hair this way or that way, and sounding like a totally different character.

But the throat just kind of falls into line once you realize in your head what it is. You got to remember the musicality of a character you're going to do.

It's very hard to take a character out of nothing, and put a hook on it, especially because it's only sonic. Futurama is a sonic world, and everyone's attention is focused on that sound and that little cartoon image. You can change it.
