For those who understand, no explaination is needed...For those who don't, none will do.

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

I tell young comics, 'Do you want this badly enough? It's there. But you have to go get it. And if you think I'm going to give you the key to the lock of that door, there is no key, there is no lock, and there is no door.'

When I would be myself, I was being big-headed. I was being egotistical. I was a megalomaniac, when it really was just having not to be a monkey for a few hours a day. And fulfilling the need to be a man.

If I found the cure for dystrophy tomorrow, I would do a telethon in four weeks for acute pain that in this country is a bigger problem than cancer, heart, sickle cell, anemia, name it. It is - it's hitting 70 million Americans.

When I hit around 65, 66, I started to feel tremendous worth and incredible personal esteem. I was becoming very cognisant of my contribution to the American spirit of helping your fellow man and all of the good stuff.
