After dinner at Monk's, Audrey passes up trying Jerry's apple pie, and starts tensely shaking her head when he insists. Jerry is perplexed that she gave no reason for refusing, despite having a sweet tooth.
Kramer sends Elaine to a downtown store to see a mannequin that looks exactly like her, and George, needing a suit for a job interview, goes along. Elaine demands to know where the uncanny mannequin came from, but a haughty saleswoman does not take her seriously. The saleswoman sells George on a perfectly-fitting suit, the last one in stock, and tips him off to come back later to get it on sale.
Kramer is plagued by a chronic back itch, and takes Jerry's spatula as a backscratcher. At Monk's, he finds blissful relief at the hands of Olive, a cashier with long nails.
George stands guard over the suit, clashing with another short, bald man who also wants it on sale. George ends up seeing the "Elaine" mannequin get undressed. On sale day, both men arrive before the store opens; having hid the suit beforehand, George claims his prize and gloats.
At "Poppie's", Audrey's father's restaurant, Jerry cannot let Audrey's pie refusal go, to her irritation. In the men's room, Poppie promises to personally cook for Jerry, but does not wash his hands after using the toilet. After watching Poppie knead pizza dough in horror, Jerry tensely shakes his head in refusal when the pizza is served, but cannot bear to tell Audrey why. Audrey assumes Jerry is getting back at her.
Elaine gets recognized in public from the store mannequin, and returns to find it dressed in lingerie, and posed getting an erotic spanking from a male mannequin. Elaine threatens to sue, distracting the saleswoman long enough to abscond with the mannequin in Jerry's car.
George goes to his interview at a restaurant, but his new suit pant legs rub together noisily. He is terrified because he heard the company fired someone for less, but the interviewers reassure him that it was for failing to toe the line. When a pie is served for dessert, George spots the chef, who turns out to be the man from the store, watching. George tensely shakes his head as the interviewers peer pressure him to eat. He loses the job for his dissent, but avoids the chef's tainted pie while the interviewers all get sick.
Jerry finds out that Audrey had apple pie at Monk's by herself, and confronts her again at Poppie's. A public health inspector arrests Poppie for sanitation violations, allowing Jerry to be smug.
Having stopped itching, Kramer also stops seeing Olive but needs an excuse to "let her down easy". With the lingerie-clad mannequin still in Jerry's car, Kramer gets in and fakes an impromptu makeout session with "Elaine", to Olive's confusion. Jerry never finds out why Audrey refused the pie, and Elaine's search for the mannequin creator hits a dead end even as "Elaines" appear in stores nationwide. Unbeknownst to Elaine, Ricky the TV Guide fan created them in tribute to her.
