"The Sponge" - Season 7 Episode 9 of Seinfeld Premiers
"The Sponge" is the one-hundred & nineteenth episode of the NBC sitcom Seinfeld.
This was the 9th episode for the 7th season. It aired on December 7, 1995.
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 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 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 (guest star 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 the wishes of Jerry. 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. 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.
