George successfully delays his wedding until late June, three months after it was supposed to take place. Jerry goes out with Susan’s best friend. Jerry loses a jacket he borrowed for dinner at the Friars Club. Kramer tries polyphasic sleep, also known as Da Vinci sleep. J. Peterman hires a hearing-impaired employee and Elaine suffers the consequences, when she gets loaded with most of his work. Elaine questions the employee’s disability and coerces Jerry to test him. The results are inconclusive, and Elaine has some fun testing him by swearing her love for him. Elaine’s boss overhears, and gives them two tickets to the magic show where Jerry lost his jacket the night before. Elaine is pressured to attend by her boss, who suspects Elaine’s remarks to Bob Grossberg (the practically “deaf” employee) were not sincere.
Kramer and Jerry are not pleased with the new “low-flow” shower heads that the building’s maintenance department has installed. Elaine is surprised to find out that opium was present in the urine sample she gave at her physical in preparation for her trip to Africa. Mr. Peterman, once an opium addict himself, tells Elaine that she will not be able to accompany him to Africa after all. Jerry’s Uncle Leo complains about an overcooked hamburger and says the cook is anti-Semitic, which Jerry jokes about on the Tonight Show. Leo’s girlfriend laughs at this, Leo calls her anti-Semitic, and they break up. Elaine discovers her opium results were from her eating poppyseed muffins.
Elaine strains her neck trying to get a bike down from the wall. In pain, she claims that she would give up the bike to whoever fixes her neck, not expecting anyone to take the promise literally. Kramer saves the day and wants the bike. Elaine complies, but later, her neck pain returns. When she requests Kramer return the bike, he tells her that it is common sense that she should have been sleeping on a board for a week after the chiropractics. The pair decide to have Newman decide who should keep the bike. In a reference to Solomon, Newman decrees that the bike be cut in half, with both Elaine and Kramer receiving one half. George gets upset when his friends steal his unique baby name.
Elaine dates a jazz saxophonist and Jerry tells one of the band members that the saxophonist and Elaine are “hot and heavy”. Susan’s parents meet and have dinner with the Costanzas for the first time, where both families obsess over a loaf of marble rye bread that wasn’t served with the meal, which Frank takes back home. George thinks that by getting Susan’s parents out of the apartment for one evening, he can get a new rye and place it in the kitchen, making it appear as though it had always been there. Kramer takes over a friend’s horse-drawn carriage for a week and feeds the horse Beef-A-Reeno, the same night he is scheduled to take Susan’s parents on a hansom cab ride.
Elaine befriends Susan. Jerry meets his pool guy outside a movie, and then he can’t get rid of him. George is worried by Elaine wanting to get to know Susan. Kramer’s new phone number is similar to a film information line. When Kramer keeps receiving wrong numbers, he begins giving out the information for movie show times à la Moviefone.
George breaks up with a woman after she beats him in a game of chess. When he tells Jerry about it, they both realize that they have done nothing with their lives and decide they are going to make some changes. Elaine comes in and tells Jerry and Kramer that a barking dog is keeping her from getting a good night’s sleep. Kramer says he knows someone who can “fix her problem”, Newman. George, after contemplating what to do with his life all afternoon, finally decides to visit his old girlfriend Susan Ross and propose.
