Dave is 60, but Oprah doesn't think he seems like a 60-year-old. "You remember when we were younger and our parents were 40, they seemed 60? That's why 60 is the new 40—because you don't seem 60 at all," she says.
One reason Dave may not seem 60 is that he has a 3-year-old son, Harry. Does Harry think his dad is funny? "Mommy has to tell him a lot that I'm just teasing," Dave says. "We kind of have to do that with our audience every night, too!"
