I don't want to go back to sitcoms - I'm a middle-aged, white guy - the high school principal who's a buffoon. It's hard enough raising kids now a days, and I don't want to be a part of a show that I'll be embarrassed watching shows like that with my kids and my mother. A lot of shows feel they need to get that for humor. You've have to have had a life experience; otherwise, it's toilet humor. If you've had a job before or experienced something, you get it. Some of these people haven't and they look for the cheap laugh.

It was the last generation of writers [ the Cheers] that had grown up reading books instead of watching TV. So you weren't getting anything that was derivative of I Love Lucy or Happy Days. You were getting real characters [like those] they read in P.G. Wodehouse or Dickens or somewhere along the line, because they had all grown up with a love of literature.

I remember being fascinated by the graduated sizes and perspective on the sets [of Star Wars]. And how they put shorter people and kids in the uniforms and placed them in the distance to give the idea that these sets had more depth than they really did.

One of the high points in my career came from a time I had with Tim Conway on a film when I had him fall down with laughter. I had this scene with him where I was this mechanic down fixing his car. I can't remember what my line was as written, but they were okay with me doing a made-up line. So Tim asks me what's wrong with his car, and I look up and say, "Well, looks like you got a squirrel caught up in there."

My uniform [in Star Wars] was cool. Not much else I can think of at the moment. You know, you don't know the enormity of these kinds of films until well after you're done.

All over the US, there is a need to teach young people to, really, get them out in the backyard, building treehouses, fixing bicycles, because you become a better, more well-rounded, Renaissance personality if you actually know how to do things with your hands. If you can fix the screen door or replace your old garbage disposal, even change the tire on a car, a lot of people don't even know how to do that. We're literally running out of people who know how to do those things, the essential things like plumbing, carpentry, stone masonry, we're literally running out of them.

When I go to the garage to pick up my clubs, I clean the spider webs off.
