Walking down the street, Jerry and George meet Elaine and her friend Wendy, a physical therapist. Jerry regrets once kissing Wendy on the cheek because now he has to kiss hello every time. George asks Wendy for treatment for a sore arm. Later, they discuss Wendy's 1960s-style hairdo that Elaine wishes she would change. Because only the bluntly frank Kramer would dare comment on it to her directly, they introduce him to her. However, Kramer loves the haircut, and tells her so. Flattered, Wendy starts dating him. At Wendy's clinic, George is angry with her because he is charged for an appointment he missed due to a family emergency, because of her 24-hour cancellation policy. Kramer plans to put each tenant's picture and name up in the building's lobby so everybody will know each other. Jerry doesn't like the idea, so Kramer takes a surprise photo of Jerry for the wall. Jerry is unhappy when he finds himself obliged to engage everyone in the building in conversation and getting kissed hello by several of his neighbors. He finally tells them he is uncomfortable with being kissed. As a result, he is ostracized, the superintendent refuses to fix his shower, and his picture is defaced. Jerry's Nana calls him to open up a bottle of ketchup. When Jerry goes to her apartment, Uncle Leo is also there. Nana reminds Leo to give $50 to Jerry's mother, Helen. Nana, who has been confusing past and present, is referring to an incident from Leo and Helen's childhood. Jerry asks his father, Morty, if Leo ever gave Helen the $50. An angry Morty calculates what the interest would be on $50 after 50 years, but Leo refuses to pay, saying they have no proof Nana's story is true. Leo puts Nana in a nursing home, presumably to stop her from talking about the $50. While visiting Nana at the home, he learns her old friend Buddy is also there. Buddy confirms the exact details of Nana's story, and Jerry declares Leo busted. Wendy cancels her appointments to go skiing with Elaine. George points out the irony that she gave only a few hours notice. Upon returning from skiing, Wendy won't drive Elaine all the way back to her apartment due to one-way streets, and ends their friendship in the process. Elaine is forced to carry her ski equipment the remaining three blocks home and injures her arm. She is infuriated when Wendy tries to charge her for treating the arm, so she and George both ridicule Wendy about her hairdo. Kramer has a party in his apartment with the other tenants. When Jerry stops by to use his shower, Kramer tells him that he broke up with Wendy because she changed her hairstyle. He won't allow Jerry in because of the visiting tenants ostracizing him.
