Al Roker — The longtime “Today” show weatherman went for bypass surgery after multiple failed diet attempts. In just eight months, Roker lost 100 of his 320 pounds and his waist size whittled from 54 to 40 inches. He even ran the New York Marathon in 2010. And, yes, one of the side effects of his surgery is that he admitted “sharted” at the White House when he thought he was releasing gas as a result of the procedure.
