Jerry has dinner with George, who eats slouched while talking, chews with his mouth open, and messily slurps. Elaine has dinner with a friend, Cynthia (Maggie Wheeler). George despairs at ever meeting a woman and abandons all hope, while Cynthia, bitter over "good" and "mediocre" men alike, contemplates dating an utterly desperate man.
Comparing notes, Jerry and Elaine consider fixing up George and Cynthia. They immediately think better of it, but both turn defensive over the other's reluctance. They pressure each other into setting up the date, and agree to exchange all inside information they get.
George demands impossibly specific details about Cynthia's looks, while Cynthia is briefed on George's unemployment, girth, and balding. Nevertheless, they agree to meet. Kramer hands out a bag of free condoms from his friend Bob Sacamano's workplace, and George accepts one, just in case. On their date, George and Cynthia have sex—in George's kitchen, to cope with his anxiety—and swear each other to secrecy. Jerry and Elaine both find out, but play dumb with each other.
George is on edge over Cynthia not calling back, but forcibly stops Jerry from intervening. Kramer warns George that the free condoms were defective, while Elaine learns that Cynthia has missed a period. Jerry and Elaine blame each other. Kramer stops George and Jerry fighting over Cynthia, assuming they are in a love triangle; George assails Kramer over the condoms, forcing Jerry to step in; and Kramer stops Jerry and Elaine's fight, assuming they are having a lovers' tiff.
George overhears about Cynthia's missed period. Elated over achieving fatherhood, he pledges his full support for Cynthia's autonomy and welfare, winning her over. Cynthia's period turns out to be a false alarm. Later, at dinner, Cynthia witnesses George's eating habits in dismay.
