I have a loyalty that runs in my bloodstream, when I lock into someone or something, you can't get me away from it because I commit that thoroughly. That's in friendship, that's a deal, that's a commitment. Don't give me paper - I can get the same lawyer who drew it up to break it. But if you shake my hand, that's for life.

I think the cartoons that they're children are watching, particularly 'The Simpsons,' they're OK. I think that the adult audience is making much too much of the danger that they imply. That's not the case. The danger for children today, honey, is the news. Keep them away from news on television.

Don't you understand how dramatic it is to be a comic? To be a fool, to get people to laugh at this show-off? Milton Berle could take Laurence Olivier and stick him under the table if he wanted to. And so could I.

If you think childlike, you'll stay young. If you keep your energy going, and do everything with a little flair, you're gunna stay young. But most people do things without energy, and they atrophy their mind as well as their body. You have to think young, you have to laugh a lot, and you have to have good feelings for everyone in the world, because if you don't, it's going to come inside, your own poison, and it's over.

The doc told me I had a dual personality. Then he lays an 82 dollar bill on me, so I give him 41 bucks and say, 'Get the other 41 bucks from the other guy.'

(The Nutty Professor) was a labor of love. It was a total film. It was the most productive, creative work of my life.
