If everyone else is doing something, I have little or no interest in it. If you're known as this guy who can do any kind of sound or voice or whatever, somebody will go, "Do you do Christopher Walken?" "No." "Well, why not?" "Because everybody else in the world does it." My carpenter does Christopher Walken.

Robin Williams understands sonic performances. He understands what it's like to change your voice up.

I'm not angry. Everybody thinks I'm so angry because I have a point of view. They're expecting me to just be all Smucker's Jam.

John Kricfalusi wanted me to quit the job when he got fired in 1992. But the problem there is that I wasn't his partner. I was a hired gun. And then people badmouth me for 10 years, like a rock in my shoe in that camp. It's a very small but active group of posters, as I've come to find out. But the thing is that I finally got to the point where, "Okay, I get you, I get it you don't like that I did what I did." But the thing was, the whole story was cockeyed. They said I put everybody out of work. No, I didn't. Everybody was going to be out of work if I didn't continue the Ren & Stimpy show.

Somebody's real voice is probably the hardest one that somebody could attempt. The characters are all, believe it or not, rooted in a reality of some sort. I've met and talked to people, and they're also fusions of showbiz periphery. But the best thing was, if you did your own voice and you were the star of the show - if it came to blows and they had you on the ropes and you had to leave, then they could just get someone to sound exactly like you.

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.

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.
