There's an awful lot of scenes where we don't know what the scene's going to be about, we ask the audience, pick a place that the scene is happening, pick the relationship, tell us who they are, things like that.

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.

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 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.

The show is probably 60 percent improvising and 40 percent not. So there's quite a bit of it that we do have prepared and that part of it, you have memorized and you've rehearsed and you're prepared, just like any show.

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.
