Aqua Teen Hunger Force (2000)

S3E9 Diet

In a contest for a case of beer, Meatwad, Carl, and Shake compete to see who can shed the most weight. Carl resorts to a unique candy bar to help him trim down, while Frylock opts for a more traditional approach to assist Meatwad in losing weight. Meanwhile, Shake focuses on sabotaging the efforts of his friends instead of participating in the challenge.
