Anytime Sam sat down to eat in public, people would come and ask how he could stay so thin. He was always stuffing his face with a lot of fatty food. They asked if he had a secret magic diet. He didn't have a diet, but he did have a magic secret. He had the ability to switch bodies. Any time he felt like he was gaining weight, he'd just swap bodies with someone thin. In fact, he just swapped bodies with a skinny Asian woman. The first thing he did was go out and pig out on some doughnuts. Sure enough, with his mouth full, a person came up to him and asked how he managed to stay so skinny.
