What was your worst puppet experience so far onstage?

Oh, the greatest night was the post-coital scene with Princeton and Kate, and he wants to go to Brian and Christmas Eve's wedding. And Mary and I are standing downstage with the puppets, and we go into the kiss. There's a big dramatic music swell, the puppets make contact and Princeton's eyeball falls off, right onto the stage. And all that's underneath it is a white X of tape, like someone did a sloppy, quick repair job on him. And, thank God, the lights were going down. I think the first couple of rows saw it, but it was pretty hard to keep it together after that. And then we go right into the wedding scene, and I was just barely hanging on. I couldn't remember my lines. All I could think about was, "There's an eyeball lying onstage right now. And we're all walking over it."

And, as an actor, is this your first experience with onstage nudity?

Yeah, actually… wait a minute, let me think back… I guess, well professionally … (laughs). No, yeah, it is. And you know what's really funny about that scene? That's when people get really offended. Occasionally there will be people that walk out when the puppets are having sex. And I'm thinking, if you didn't walk out earlier when we were singing "Everyone's A Little Bit Racist," but now you're walking out because two people onstage are rubbing their arms together? What?! It's really funny to me. Actually, when the lights are kind of dim on us when we're doing that scene, I kind of keep an eye out on the crowd to see who's getting uncomfortable, who's going to leave. And the best is when there's a little kid in the front row, who shouldn't be there.

Do they say what age is appropriate for the show? 10 or something?

I think they say 14, actually. And I don't know how they get those front row seats, because we do a lottery, so I don't know how those kids … they must have somebody wait in line for them. I don't know, but they gotta learn sometime.

I was also amazed when I saw that show in that, you don't seem to stop moving ever?

No, it's a marathon of a role. The weekends are the worst because it's a four-show weekend, two Saturday and two Sunday. So by Sunday night, I just crash and I'm no good to anyone until late Monday. (laughs)

Yeah, because there were times when you're coming through the door with another character on your arm, and I couldn't figure out how you got over there so fast, let alone switch off puppets.

There's a lot of people helping me backstage.
