How do these celebrities stay so impossibly thin? Simple: They have full-time personal trainers, who advise them on nutrition, give them pep talks, and shoot them with tranquilizer darts whenever they try to crawl, on hunger-weakened limbs, toward the packet of rice cakes that constitutes the entire food supply in their 37,000-square-foot mansions. For most celebrities, the biggest meal of the day is toothpaste (they use reduced-fat Crest). - Dave Barry
