When a man eating Chinese food won't swap him for a plate of salad, Simmons gives up his firstborn son for a single grain of white rice, smothered in a half-dollop of moo-shu sauce. His son grows up to be the Glendale Fitness Authority, in charge of an ""anti-fatties"" organization. During a roundup of fat people, the Fitness Authority's birth parents are lured out with promises of ""free chocolate"" - but Simmons is rescued by the Fat Underground before he can be sent to the work-out camps. When the Fitness Authority learns Simmons is his birth father, he attempts to understand why his father abandoned him by eating a muffin from the Happy Bakery, shaped like a father giving up his baby. Also featured is Moleman's ex-girlfriend, who is heartbroken when Moleman won't come to the surface to meet her parents. (thetvdb.com)
