My son Barry, of course, has been on from the beginning. And his son Shane is playing now a med student regularly on the show. And at one point or another, I've had all four of his kids on the show.

Bob Hope, like Mark Twain, had a sense of humor that was uniquely American, and like Twain, we'll likely not see another like him.

I decided, when I started having kids, that I'd try not to do anything that I wouldn't be proud for them to see. I've kind of stuck with that, and I don't regret that at all, although I've lost money and passed up a lot of projects because of it. But I feel good about that.

My brother and I laughed a lot as kids. We came up in the middle of the Depression, and neither one of us knew we were poor. We had nothing, but we didn't know it.

Otherwise, everything got better and better, just one surprise after another. And that's why I wrote the book about a matter of being in the right place at the right time, and just luck.

In my seventies, I exercised to stay ambulatory. In my eighties, I exercise to avoid assisted living.

So as my kids will tell you, they had a pretty normal life.
