Never take "NO" for an answer.

Before there can be wonders, there must be wonder.

I went to visit Frank Capra, one of my idols, and did a kind of Judd Apatow interview with him. I said, "I'd like the Statue of Liberty to disappear, but I want to do it as a lesson in freedom, how valuable freedom is and what the world would be like without liberty." And Frank Capra looked at me and said, "David, I love your idea, but here's what you're going to do. You're going to try and it's not going to work; it's not going to disappear." And I said, "Mr. Capra, I can't do that."

I'm a big fan of the Pixar movies, and Ed Catmull, who wrote a book about his experiences producing them, talks about how it takes three or four years to get it right.

My show is constantly evolving... new tricks are added, old ones are dropped... so it stays fresh. But it's the randomly selected participants from the audience that make it fresh and provide some of the best comic relief.

I record that I was born (as I have been informed and believe) on a Friday, at twelve o'clock at night. It was remarked that the clock began to strike, and I began to cry, simultaneously.

Magicians lose the opportunity to experience a sense of wonder.
