Synopsis by Josh Ralske
At the supermarket, a security guard mistakes the portly Chris (voice of Seth Green) for a shoplifter. "Oh, you're just a fat kid," he acknowledges. Brian (voice of Seth MacFarlane) uses acupuncture to deal with his flea problem, and it doesn't work. The Griffins hire some military-style exterminators, who use automatic weapons and hand grenades to combat their bug problem. Brian puts the family up in a hotel while the house is deloused. The family swims in the hotel pool, but Chris sits on the diving board, ashamed to remove his shirt. Lois gets Peter (MacFarlane) to help Chris with a diet and exercise program, but when that doesn't have quick results, Peter decides to take him to see Cleveland's brother, Broderick (voice of Mike Henry), a plastic surgeon. Chris balks at liposuction, and Lois is proud of him, but Peter comes home looking surprisingly svelte. Now he can fulfill his lifelong dream of putting a saddle on Brian's back and riding him like a horsey. Chris continues trying to lose weight the old fashioned way, with Stewie (MacFarlane) mocking his efforts and teasing Chris by gorging himself in his presence. Soon it's Stewie who has the weight problem. Meanwhile, Peter has more work done, and is admitted into the Quahog Beautiful People's Club. Lois is torn, because while Peter has become "a superficial, egomaniacal jerk," she's really attracted to him. Peter tries to bring Chris to the club with him, and when his son is denied entry, Peter defiantly proclaims, "Well, if my son can't come in, then I'll just come in. See ya at home." Later, Peter is distracted by his image in the rear view mirror while driving, causing an accident that changes everything. This episode features voice work by Jay Mohr and Gary Cole.
