Demi's Senior Moment

America's sweethearts, Ashton Kutcher and Demi Moore poked fun at the yawning chasm between their ages he's 27, she's 42 during his opening monologue on "Saturday Night Live" this week. Kutcher, guest-hosting for the second time in his young life, immediately pointed out Moore, a k a "the best thing that has ever happened to me," sitting in the front row. Kutcher then invited his love to join him whereupon she got up and, with the help of her walker, started making her way to the stage. "Hurry up, it's a live show, baby," Kutcher said. "My support hose are cutting off my circulation," Moore joked back.
