I might have skipped class, but I didn't miss any lessons.

I don't have a set of tenets, but I live an ethical life. I practice a humility that presupposes there's a power greater than myself. And I always believe, don't inflict harm where it's not necessary.

I always felt that I came up short in the education department, but I've come to the conclusion that we all get an education.

I mean, I enjoy my work as an actor. But to make a difference in people's lives through advocacy and through supporting research - that's the kind of privilege that few people will get, and it's certainly bigger than being on TV every Thursday for half an hour.

That's the way I look at things - if you focus on the worst case scenario and it happens, you've lived it twice. It sounds like Pollyanna-ish tripe but I'm telling you - it works for me.

I didn't just want to be a poster boy and sign on to publicize somebody else's method of operations. If I was going to put myself out there, I wanted to make sure that it was to an end. So I got involved with this congressional hearing about Parkinson's being underfunded.

You've probably read in People that I'm a nice guy - but when the doctor first told me I had Parkinson's, I wanted to kill him.
