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.

It was actually what my dad did and with the Muppets, the years with the Muppets, it was really all targeted to adults. It was in a time when everything had to be safe for the whole family. But he was targeting adults.

And it was a whole lot of fun, and in many ways, what we've done with the show is just taken that part of my early memories of visiting my dad, shooting with the Muppets, and taking that and making a show that's really an expansion of that and presenting a show that's all that.

We try to keep it a classy show, but it certainly is blue at times. And it all depends on the audience, sometimes we've have audiences that don't really want us to go too far in that direction.

I think initially it's terrifying because going into a show where, you know, "Oh, I'm going to be on stage for two hours, I have no lines to memorize, I have nothing really prepared," and actually I say that, the show is not all improvising.

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.

We took a show to the Aspen Comedy Festival, called "Puppet Up" at that point, and in Aspen we just did three shows, and in Aspen, there was a producer from the Edinborough Fringe Festival, who said, "Please come to Edinborough."
