Actor Ashton Kutcher is begging his wife Demi Moore to take to the stage on an upcoming U.S. TV game show he is producing. The new series, called Opportunity Knocks, quizzes family members on how well they know each other. And Kutcher, who is stepfather to Rumer, 19, Scout, 16, and Tallulah, 14 - Moore's daughters with action star Bruce Willis - is convinced his handsome Hollywood family would make the perfect team. He says, "She'd be a genius. I actually think that in general the moms on this show are going to do a lot better than everybody else in the family."
