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.

Oh, well, I can't tell you; it would be telling you the end. It's a one-character lip-syncing because in the early days, that's what my dad was doing.

People would say to him, "When you finish a movie, did it come out as good as you thought it was going to?" Or, "Did it come out the way you intended it to come out?"

I was already sort of mixing my science physics enthusiasm with entertainment and directing and puppetry.

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.

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.
