I went through puberty late. I was a little, little, tiny kid. I was still growing in college.

I had just left 'Saturday Night Live' when I came to 'The Daily Show,' and it just felt like Jon was on my side. I'll always be grateful to him for that. I just got the impression he wanted me to succeed, and then I wanted to succeed for him. I think that's good leadership.

In the Marine Corps, I was used to people doing what they said and saying what they mean. There was a higher purpose and calling in the Corps. Everyone works toward accomplishing something together, and there's a common goal. In entertainment, the same isn't always true. You're in it for yourself in Hollywood.

Just take yourself back to September 2001. As that month went on, and as that autumn unrolled, everybody wanted to do something. How can I help? Do you want my blood? Do you want money for the victims? I was a captain in the Marine Corps. I knew what I could do. I was right there. I was ready. I saw it. I moved the rubble with my own hands.

Too much comedy is filthy these days. There's nothing they won't say. I like Jimmy Carr, but I don't like the language he uses. I don't understand why he feels it necessary; I find it extremely offensive.

What holds you back in comedy is fear.

We can't understand when we're pregnant, or when our siblings are expecting, how profound it is to have a shared history with a younger generation: blood, genes, humor. It means we were actually here, on Earth, for a time - like the Egyptians with their pyramids, only with children.

Isn't it funny how babies laugh a lot? I read a toddler, a young child laughs 300 times a day. The average adult laughs, like, four times a day. God put it in them. He put the laugh in us, but I think sometimes we let life get us down, you know, have bad breaks, and we lose our breaks.
