"The Non-Fat Yogurt" - Season 5 Episode 7 of Seinfeld Premiers

"The Non-Fat Yogurt" is the seventy-first episode of the NBC sitcom Seinfeld.

It was the 7th episode for the 5th season. It aired on November 4, 1993.

Plot Summary:

Jerry, Elaine and George eat at a non-fat frozen yogurt shop in which Kramer has invested. The yogurt is delicious, and they (along with Newman) indulge, as it is "non-fat." When Kramer notices that Jerry and Elaine have gained weight, they become suspicious of the yogurt's contents. Elaine decides to send the yogurt to a laboratory for testing.

Meanwhile, Jerry accidentally uses the word "fuck" (which is censored) while near the shop owner's son, who starts to use the word frequently. When he tries to apologize, the boy ruins a tape of one of his stand-up routines, leaving Jerry cursing yet again. Elaine's new beau and George's nemesis, Lloyd Braun works as an aide to the mayor of New York City, David Dinkins, currently up for reelection against Rudy Giuliani. Elaine suggests that everyone in the city wear name tags, so that they can greet each other. Lloyd takes the idea to Dinkins, much to everyone else's ridicule. Braun eventually breaks up with Elaine; she claims that it is the fault of her weight gain from eating the yogurt.

Kramer, fearful of losing his investment, tries to sway a lab technician to falsify the analysis of the yogurt. In the process, they kiss passionately, and a sample of blood with high cholesterol falls into the test tube belonging to Rudy Giuliani. In the end, though, the lab reveals that the yogurt contains fat. Business plummets, especially when Giuliani receives the results of a physical claiming that he has high cholesterol. Giuliani reveals that he, too, has eaten a great deal of frozen yogurt lately, and vows to eliminate false advertising in the city. The yogurt shop closes down, leaving Newman furious. The episode ends with the main characters watching Giuliani deliver his victory speech over Dinkins; the "name tag fiasco" cost him the election.
