And one of the funnest things was watching what they did before the director called action and after the director called cut. And they'd keep their hands in the puppets, they'd stay in character, and then they'd start goofing around with each other and be off of script, and it would get quite blue.

The first big thing that I did with my dad was the bicycle sequence in "The Great Muppet Caper," where Kermit and Piggy are riding bicycles in Battersea Park in London and that was a complex marionetting and cranes driving through the park, it was a complicated scene, and I did that with my dad.

We wanted to premiere it in New York, because New York is sort of the home of the Jim Henson Company and it's sort of the tone and flavor, always, of the puppet work that we've done traditionally. And that's what brought us here and now we're here.

First of all, you're improvising through a puppet, so you're not always yourself: you're a cow or you're a pig or you're an old woman, you know, whatever puppet you pick, or you're a demon, you know, whatever you pick up, that's what you get to be in the scene.

I always very much enjoyed arts and it was so central in my family, my mother was also an art teacher, as well as founding the Henson Company with my dad, there was a lot of art going on in our household.

The challenge is, well, there's a huge challenge, which is when you're improvising, you're meant to sort of clear your mind completely, just be open and funny, and paying, you know, paying attention.

But the fact that most of the show you can't be prepared for, you have no idea really what's coming is initially very nerve wracking, by now, it's kind of fun.
