When you're a short actor you stand on apple boxes, you walk on a ramp. When you're a short star everybody else walks in a ditch.

I remember my son wanted to go to bed with his cowboy boots on, and we had this fight for like an hour. Then I realized that the only good reason I had for him not to do it is because I didn't want him to. There was really no other reason. And finally I said, "OK, fine." It was a great victory for me, because I realized it doesn't really matter.

When I was younger, I was always described as happy-go-lucky. Then I drank and I partied - did all that stuff that might tell you maybe there was a little bit of untruth in that [description]. Now, the surprising thing is that when I say stuff, I actually mean it. I don't have to do the work of trying to formulate my point of view. It just is. And it's surprising how much I love life. I just really have a good time.

If you fixate on the worst-case scenario and it actually happens, you’ve lived it twice.

The secret to a good marriage, as far as I am concerned, is a joke I make: Keep the fights clean and the sex dirty.

If you were to rush into this room right now and announce that you had struck a deal - with God, Allah, Buddha, Christ, Krishna, Bill Gates, whomever - in which the ten years since my diagnosis could be magically taken away, traded in for ten more years as the person I was before - I would, without a moment's hesitation, tell you to take a hike.

I happen to be a Parkinson's patient. I'm not fearful of my condition or my future - but if someone is looking in my eyes for fear, then they see their own fear reflected back at them.
