I am forever grateful for Cheers.

My job playing Sam Malone was to let the audience in, to love my bar full of people. And that informed my life. I mean, we're so different [in the cast], some of us. Miles apart. [But] when I see anyone from those days, I tap into that instant love for them.

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

The planet will survive. Whether we get to be here and enjoy it, or enjoy life as we've known it, is what's questionable.

We are so arrogant, we forget that we are not the reason for evolution, we are not the point of evolution. We are part of evolution. Unfortunately, we believe that we've been created to dominate the planet, to dominate nature. Ain't true.

How much do you engage yourself in what's truly real and important in life? That's the individual question.

At the time, my 6-year-old kept thinking my character's name was "Sam Alone," which is kind of brilliant. The funny came out of Sam's sad core: the alcoholic, the sex addict, the person who thinks he's God's gift.
