Sure, the comedians who swear or use scatological humor can get laughs, but they're uncomfortable laughs.

I have been raising money for the past 14 years for diabetes research.

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 don't know that I ever did see Star Wars as any different. I was certainly proud that I did it.

So many people aren't ready for Hollywood - professionally or practically.

I mean, Cheers [from the Star Wars] was just a job while we were doing it. All of us were really only hustling to pay the rent, weren't we.
