Peter tries to help Chris lose weight, but when working out for a week doesn't make a difference, he resorts to liposuction. Chris is scared off by the plastic surgeon, but Peter undergoes the operation and ends up a big stud. Lois is disturbed when she disapproves of Peter's decision, but can't help being attracted to her new studly husband. Peter is inducted into the Beautiful People's Club of Quahog and shuns his 'normie' family. Peter, distracted by his own reflection in his rear-view mirror, crashes his car and lands in the Quahog Lard Factory. When the bandages are removed, he looks like his old self. Stewie, while tormenting Chris on his diet, gains an enormous amount of weight and becomes so roly-poly that he can't even reach his own mouth with his hands.
