As the years went on, the audience has become very jaded. They've heard every joke, they've seen every story line, they know where you're going before you even start to get there. And that's a hard audience to keep interested.

I just make it my business to get along with people so I can have fun. It's that simple.

The writers are the stars of every really successful sitcom.

I've worked with the Los Angeles Zoo for 45 years, and we have this magnificent photographer, Tad Motoyama. He takes these wonderful, wonderful animal pictures. All through the years he's given me copies of these pictures. Well, I have all these gorgeous ones, so I said, 'Tad, I want to do a book with your picture on one side.'

You're never too old for anything!

If you call me a comedian I will be very grateful. I will thank you profoundly. No, I love doing comedy. It's fun once in a while to do a serious part but I really enjoy doing comedy because I love to laugh.

I am interested in a lot of things - not just show business and my passion for animals. I try to keep current in what's going on in the world. I do mental exercises. I don't have any trouble memorizing lines because of the crossword puzzles I do every day to keep my mind a little limber. I don't sit and vegetate.
