So that's the challenge, you have a big technical aspect of what you're doing whilst you're creatively trying to improvise.

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?"

A puppet that starts to improvise badly is almost funnier than the puppet that's improvising well. So the show gets better when the improvising is really good, but also the show can also sometimes get better when the improvising sort of goes a little wrong and that's sort of a blessing to improvising with puppets.

I thought, well, if we're inviting an audience, let's do it right. So I put in a proper studio audience at our studios in Los Angeles and it was just a little showcase and it was just for fun.

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.

But initially when I was working with my dad, it was in special effects puppets with radio control and motors and puppet effects.

The first show that my dad and my mom did together was for, was a comedy series, a short form that went in the middle of late-night news, and then through all of their career, it was always the "Ed Sullivan Show," it was a variety act, my dad was on the "Jimmy Dean Show" for a few years.
