I've met a lot of rock stars when they come to The Simpsons, and almost every one of them I get really freaked out.

It's always impressive when talented comedians are easy laughers or generous with their laughs.

I've done literally 100, 150 different characters. Some of them have only appeared for a line or three. But the point is, every sound I can make has been harvested.

Getting over someone is a grieving process. You mourn the loss of the relationship, and that's only expedited by 'Out of sight, out of mind.' But when you walk outside and see them on a billboard or on TV or on the cover of a magazine, it reopens the wound. It's a high-class problem, but it's real.

Being funny with a funny voice is more my comfort zone, a broader character that I try to humanize, a kind of silly or wacky persona that I try to fill in.

Godzilla's a monster for the '90s. He's been working out.

I just really committed to trying to never repeat myself. I'd seen actors do that on films, and I was, like, "I wanna try that once!" Ultimately, I'm much more in the school of getting one or two versions that feel right, as opposed to going all over the map. But it's fun to exercise that once in awhile.
