I don't know. I remember when I was 9 years old, I would ask the bus driver why he wanted to drive the bus. We would go to Dodgers Games in Brooklyn, and my friends would want autographs, and I would want to ask questions. My 15 year old inherited that gene from me, he is constantly asking questions. I don't know where that gene came from. That's one of the products of the Jewish faith, encouraging learning. I did not go to college, I only went to high school, but emphasis on learning and being creative. My favorite question is: Why? Because Why can't be answered in one word.

Well, the toughest part is questioning the relatives of the victims of a death - a child who was murdered, and you have to talk to their parents, or children who are missing. Those kind of emotional things are always the hardest, you don't like doing them, you have to do it, and it's always, always hard.

Former undefeated heavyweight champion the late Rocky Marciano told me that when he was a kid there was a bully in the neighborhood that he was always afraid of. That he would go out of his way to avoid running into him. And then on the night he won the heavyweight championship, The childhood bully came to see him in his locker room and for a couple of seconds he was afraid.

I was about to interview him at the Open Your Heart In Paradise retreat in Hawaii in front of the entire retreat. We were back stage and he looked up at me and smiled and I said "I'm so nervous!!!" and he said "Me too!!!!!!!" and we laughed and it was just the best. I miss him so much!

I think in the presence of a monster I get a little nervous, I think that's natural. To be humbled by someone who is "better" than you. I'm sure I make other comics nervous but all they have to do is say hi and be cool and I'll be cool. I should remember my own advice.

I do get nervous. And that's not a bad thing. What I try to do (and this sounds very cheesy, but it's helpful) is to acknowledge my fear, and then it doesn't dominate me.

Definitely. I kind of hate when I hear a performer who says they "never get nervous." I just don't believe that.
