It's really great to do one piece, "I've Grown Accustomed To Your Face," my dad developed in 1956, when he was 20 years old, and it's great to do that piece again now and see that it still really works as well as it ever did.

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.

"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.

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.

My dad and mom were, they would take what were popular hits, and lip-sync to them with puppets and do a ridiculous story.

We kind of lost a lot of that and puppeteers were sticking to the script and we thought everything needed to get a lot funnier, so we thought we would go to a good improv comedy instructor.

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