Ep 3. Weight Gain 4000

In the third episode of South Park season 1, titled "Weight Gain 4000", the town of South Park prepares for a visit from the television personality and fitness guru, Kathleen "Big" Griffin. The character is a spoof on real-life fitness personality, Susan Powter.

To make a good impression on Griffin, the town's mayor, McDaniels, decides to hold a "Student Bodybuilding Competition" in the school gymnasium. The winner of the competition will be awarded $5,000 to use towards physical education equipment for the school.

Meanwhile, Cartman becomes excited about the competition when he learns that "Big" Griffin will be attending and decides to compete. However, he faces a problem when he realizes that he's overweight and out of shape. In typical Cartman fashion, he decides to take a shortcut and orders a body enhancement powder called "Weight Gain 4000" from an unsavory telemarketer named Scott Tenorman. Scott later appeared in a few more episodes as Cartman's nemesis.

At the school the day before the competition, the kids are introduced to Griffin. She announces to the students that the winner will be announced on her television show, "Getting Gay With Kids." The students are excited when they hear this and begin to train hard for the competition.

When Cartman receives his "Weight Gain 4000" package, he consumes the entire container, believing that it will make him muscular and strong. But things take a turn for the worse when the powder instead turns him into a bloated and uncontrollable mess. He becomes irrational and overly emotional, lashing out at everyone around him, including his friends.

Meanwhile, the town's political advisor, Mr. Garrison, has a personal agenda of his own. He wants to win the competition for himself and his secret lover, Mr. Slave. The two of them come up with a hilariously choreographed routine to impress the judges.

On the day of the competition, the students begin to show off their muscles and impress the judges. Cartman, whose physique is now grotesque, decides to cheat by using a rigged weight-lifting device. However, things don't go according to plan, and chaos ensues as Cartman's bloated body is sent flying through the gymnasium, causing destruction and mayhem everywhere.

In the end, the results of the competition are announced, and the winner is someone unexpected. The town learns a lesson about the importance of honesty, hard work, and determination. The episode also touches on issues of body image and the dangers of taking shortcuts to success.

Overall, "Weight Gain 4000" is a classic episode of South Park that pokes fun at society's unrealistic expectations of beauty and fitness while also delivering plenty of laughs and outrageous hijinks.
