One of the ingredients that made Cheers work so well was the great ensemble of actors we had. That's the case with any good series.

I don't think it's a matter of, do you win the game or not, it's how gracefully do you play it.

As a people, we value family, education and success. Hunger is an enemy to all three. Scientific studies have demonstrated that even brief periods of hunger can permanently inhibit a child's mental, emotional and physical growth. Kids who are hungry do poorly in school and are unlikely to grow into productive adults. For families, experiencing hunger means living in a world of isolation and shame. Caring citizens must put an end to this disgrace.

The biggest danger we face is overfishing. We literally could fish out our oceans, some scientists believe, in the next 40, 50, 60 years. We are fishing out the top of the food chain, and it's pretty crucial because about 200 million people depend on fish and fishing for their livelihood, and about a billion people, mostly in poorer countries, depend on fish for their protein. So this is a big problem. Good news is, it's fixable.

I had trouble hanging around [Shelley Long] until we stood onstage together, and then I was in heaven.
