"Stuffed and Unstrung" started as a workshop, actually, classes within our company. We found that our puppeteers were not ad libbing as well as traditionally, Jim Henson Company puppeteers have. We're sort of famous for going off script a little bit and ad libbing.

There was a producer from the Aspen Comedy Festival who happened to be there, as a friend of a friend, and she said, "I'd like to book you into the Aspen Comedy Festival," and we said, "Well, there isn't really a show to book in, this is just a little showcase and it's really our workshop." And she said, "No, it's great, I love it, just do exactly what you did."

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.

he puppeteers really responded to it. Patrick Bistrow really responded to it, it's great fun to do improve comedy with puppets.

"Sesame Street" was really the first kid's show that my dad did. He did a couple of TV specials that were targeted for kids before "Sesame Street," but really, it was, it's kind of going back to our roots, when we start to get adult. This show gets very adult sometimes, and that's because of the audience.

Where does a character come from? Because a character, at the end of the day, a character will be the combination of the writing of the character, the voicing of the character, the personality of the character, and what the character looks like.

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.
