You can't study comedy; it's within you. It's a personality. My humor is an attitude.

I don't really tell a joke per se, I build up an attitude and it becomes a joke.

What I do is, I make fun of people and I make fun of myself and things around us and exaggerate things. And I'm never mean-spirited. See, the word insult means some guy who's a real unkind human being. But I don't do that, because otherwise I wouldn't be headlining all these years, thank god, and all these people showing up to see me.

In the old days, that was my ad-lib for hecklers in the joints I worked. It stuck with me. I hardly say it now, say, to fans, even though people do send me hockey pucks.

People think being in your seventies means sitting around in a chair with a blanket over your legs, drooling.

You got to have a lot of courage. Secondly, whatever it is you're doing you have to believe in it wholeheartedly. Thirdly, you have to be able to stand up in front of people and know that they'll laugh.

I'd like to think my performance is today. I never try to - it's so, as you know, watching me, I have a beginning, middle and ending. But every night the show changes and I relate to an audience and I relate to the young people.
