Charles Barkley
In his NBA heyday, Charles Barkley was known as the Round Mound of Rebound. A much svelter but still outspoken Barkley now says in a Weight Watchers ad, "I've won like a man as long as I've been a man. Now I'm losing like one. Come on, join me." (His efforts to hawk veggies have been less successful: "Broccoli's not bad. It's just not good.") Last year the TV analyst shed 38 pounds on Weight Watchers and then got caught calling his WW gig "a scam." He later clarified: "The fact that I’m dropping pounds, getting healthier and getting paid at the same time is my definition of a great scam."
