In L.A., though, people get off busses calling themselves actors, so many are really not professionals.

You've got to write for your audience.

I've turned down projects based on raunchiness before.

Maybe, I got a sense when [Star Wars] came out, and there were always these lines around the block. We didn't understand the popularity of Cheers until maybe five years into the series.

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."

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

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.
