I always very much enjoyed arts and it was so central in my family, my mother was also an art teacher, as well as founding the Henson Company with my dad, there was a lot of art going on in our household.

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?"

Patrick thought we should try to put an audience in front of one of the workshops, basically in front of the class and see how the performers rose to having an audience there, because he said, "You know, it's a really interesting test, because sometimes it gets even funnier."

And with puppets, especially in our company, we sort of demand a very high standard of puppetry, so it's a real technical skill.

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.

I'd say that that is a challenge, but it also is, again, it's helpful. It's helpful to have the discipline of, okay, I'm doing, I'm doing something that's quite precise over here, working the puppet, and I'm doing something that's very imprecise and creative and unleashed over here, which is the comedy side. And it's kind of nice to allow your brain to be doing those two things at once.

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