TOMMY LASORDA (1988-1993)
Company: SlimFast
Shtick: Lasorda had been overweight himself, and dieters appreciated his willingness to admit that. He used SlimFast and credited the drink with his success in losing 30 pounds in three months. His visible success in losing the weight and keeping it off made him a credible pitchman.
Fun Fact: Tommy Lasorda was a big eater from childhood on. As a boy, he ate so much that his father feared he had a tapeworm and took him to the doctor. It turned out he just had a massive appetite and would eat 10 sandwiches for lunch.
