At Monk's Café, George tells Jerry, Elaine, and Kramer that his mother caught him masturbating while reading a Glamour magazine, resulting in her falling over in shock and going to the hospital. George claims that he is "never doing that again." When the others express skepticism over his ability to follow through, the four make a bet over who can go the longest without masturbating. The men put up $100 each but insist that Elaine put up $150, as they insist that masturbation is not part of a woman's "lifestyle". Kramer fails almost immediately after seeing a naked woman in an apartment across the street from Jerry's; after returning to his apartment to masturbate, he walks back into Jerry's apartment and slams $100 on the kitchen counter, saying "I'm out!". The others meet various temptations of their own; George is distracted while visiting his mother in the hospital by an attractive nurse giving another woman a sponge bath behind a curtain, Elaine imagines a relationship with John F. Kennedy Jr., who frequents her fitness club, and Jerry is frustrated because his girlfriend Marla, a virgin, is hesitant to have sex with him. The remaining contestants become irascible and suffer insomnia. Elaine is second to drop out of the contest when she succumbs in anticipation of a potential date with Kennedy. While making out on the couch, Marla asks Jerry if they can have sex, claiming that she is ready. When Jerry mentions the contest in passing, Marla leaves in disgust; Jerry then resorts to looking at the naked woman. Elaine believes that Kennedy has stood her up, but George reveals that Kennedy missed her and went with Marla. The three then see Kramer with the naked woman across the street and wave awkwardly to them. That night, everyone sleeps well, but it is not revealed whether Jerry or George won. Marla is in bed with Kennedy, having finally lost her virginity to him; enraptured, she tells him that it was "wonderful".
