How is your health?

Good. I've had about four knee operations. Other than my right knee, I can probably kick somebody like Bruce Lee with my left knee. If I jump up and fall on them, I probably will do more damage — to them.

You give a touching tribute to Muhammad Ali on your website. Have your feelings toward him changed over time?

As the years have gone by, I [realize] he is one of the greatest men I ever have met. He's too big to [merely] categorize as the greatest boxer. That makes him small. Each year that goes by, his life means more to me.

You are back on television endorsing a company called InventHelp. What is that all about?

People think I invented the George Foreman Grill. Not really. People would ask me, "George, can you help me [with my invention]?" Now I point them to someone who can really package their deal.

Estimates are that you earned in excess of $200 million on the grill. True?

Much more. There were months I was being paid $8 million per month.

What is your secret to being a successful corporate pitchman?

When that camera hits you, it's not about how good you look. People look for honesty. You sell yourself; the product almost is secondary. [Initially] I didn't want to do commercials. Bill Cosby told me, "You're just like anyone else — we would all like to be on television. Enjoy it. If you don't want to do it, send them to me and I'll do it!"
