There's not a rocket scientist, not a doctor, not an accountant that 30 years in goes, "Oh, now I'm getting it. Now I can't wait to get back out there because I'm better than ever."

I started to have panic attacks on stage and my wife just asked, "Why don't you just stop?" I was doing Ghost Whisperer at the time so I was making enough money where I could put it away and she said, "Then, when you go back, you just go up and tell the truth." And it's a lot more tiring.

You don't have to be Willy Loman about it. But, "Airline food is crazy. Hey, what's with these rent-a-cars?" or you go up and talk about how Christopher Walken wanted to know where my dog's tail went. That really happened to me.

I remember I used to go to The Laugh Factory and just goof off onstage, and then I'd see Dane Cook. He did a bit about his Mom making the bed in the summertime when he was a kid. He just said "Vroom!" and threw the sheet up in the air and the sheet would just stay over the bed for like a minute and a half. All he had were his arms out, but I could see the sheet. And he didn't do anything. He just kept it there. And I went, "I have to write more."
