'Cheers' was great. They paired me up with Shelley Long on this tiny bar set for the final audition. That was my first really big one, and we just clicked instantly - I still think I got the part because of Shelley.

I am forever grateful for 'Cheers.'

I got my first television at Stanford when I was 20, and I used to watch 'The Dick Van Dyke Show'. He played my father on 'Becker,' and he's still one of my heroes. Along with John Cleese, he's my favourite physical comedian.

Everything I am, everything I've been allowed to do, career-wise, has come out of the opportunity I had with 'Cheers'. I think it's one of the funniest shows ever. They are some of my best friends.

I try not to see Woody Harrelson because he has become this big movie star, and it grates, so I try and stay away from him.

When people are in the midst of really heavy stuff and still have a sense of humor, I admire that.
