I was 16 at the time, and I came backstage and started hanging out with them. I said, "Well, maybe you can 'vanish' the silk this way." The opening was a black stage while the "Magic to Do" song started playing. All you saw were hands, lit by Jules Fisher, and then Ben Vereen would appear beyond the hands, and at the end of the scene he would vanish a silk. The spotlight would hit a red spot on the floor where you'd see the silk on the floor. He'd pull the silk out of the floor and it became the entire set coming out of the floor.

You have to learn certain skills to present magic.

Reading [Judd Apatow] book, about his background, I think there's a great similarity. What gives him the fire to work hard? He worked hard, researching the comedians of the time, what touched him about it.

Everyone understands cards and relates to it. They have them in their homes and in their hands, so it makes them very accessible.

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."

When I was a kid, people wanted to be an astronaut. Today, kids want to be famous, and that's totally the wrong approach. You have to have authenticity in what you're doing. You have to really care about the core message of what you're saying, and then everything else will fall into place.

I was teaching magic at NYU when I was 16.
