Jerry, Elaine, and Kramer are at Monk’s Cafe and they mention that Jerry still wears a size 31 pair of jeans. Kramer also mentions the female contraceptive sponge is being taken off the market. Kramer passes both of them an AIDS Walk sheet for them to sign. While reading the list of signatures Jerry sees a girl’s name (Lena, played by Jennifer Guthrie) whom he once met, but doesn’t know her unlisted number. Jerry takes down the number and calls the girl. When George and his fiancée Susan get into a fight about sharing their secrets, in order to get back into her good graces George tells her that Jerry does not actually wear size 31 jeans.
Meanwhile Elaine goes on a 25-block radius hunt to find the contraceptive sponges. When she finally arrives at a pharmacy which still carries them, she purchases a full case. Her limited supply requires that she restrict her usage. She puts her current boyfriend, Billy (Scott Patterson), through a rigorous examination to make sure he’s “sponge-worthy.” Jerry tells George that he found his new girlfriend on the AIDS walk list. George then tells Susan against Jerry’s wishes. Susan then tells her friend, who tells a friend until the phone tree reaches Jerry’s new girlfriend. When George comes to Jerry’s apartment Jerry tells him that he is “out of the loop”, because he told Susan about Jerry.
When Kramer takes part in the AIDS Walk, he refuses to wear an AIDS ribbon in opposition to “ribbon bullies”, led one more time by Bob and Cedric from “The Soup Nazi” episode. The storyline appeared to be based on the real-life controversy of former Days of Our Lives actress Deidre Hall, who, in 1993 publicly refused to wear AIDS ribbons at public events, such as the Daytime Emmys. Hall claimed that the volunteers who passed out the ribbons bullied celebrities into wearing the ribbons.
At his new girlfriend’s, Jerry finds out that she has a lifetime supply of contraceptive sponges (assuming the boxes shown are all she has, there are approximately 720 sponges). While trying to disguise that he has seen the sponges he tells her his secret about his jeans and she dumps him.
