At Monk's Café, Kramer asks Jerry and Elaine to sponsor him for an AIDS walk. On the list of sponsors Jerry sees Lena Small, whom he wanted to call for a date, but her number is unlisted. Jerry takes down the number and calls Lena. Elaine, excited by how things are going with her boyfriend, Billy, says she is going shopping for contraceptive sponges. Kramer informs her the sponge was taken off the market. Jerry boasts that he has been wearing size 31 pants since college. George tells his fiancée Susan that Jerry actually wears size 32 and modifies the tag to a 31; this initiates a fight about sharing other people's secrets.
