Plot

George gets in an argument regarding a cancellation policy. Jerry and Elaine try to use Kramer's bluntness to deliver some much needed fashion advice.

Kramer tries to create a Utopian society when he puts up pictures of all the residents of his and Jerry's building. Jerry doesn't mind until the women of the building want to be greeted with a kiss. After Jerry objects to kissing hello, he's vilified and nearly kicked out of the building. Jerry also has to settle some family issues when Nana remembers that Uncle Leo was supposed to give Jerry's mom some money 50 years ago and Uncle Leo puts Nana in a home to keep her quiet. Meanwhile, Elaine's friend who is a physical therapist skips out on George's appointment and goes skiing instead, and they have a hard time telling her about her dated hairdo.—halo1k

Jerry dislikes Elaine's friend Wendy because she gives him a kiss on the cheek every time they meet. Wendy sports a somewhat dated hair style and neither Jerry nor Elaine really have the nerve to tell her so they come up with the perfect solution: introduce her to Kramer who is bound to blurt out some inappropriate comment. It doesn't quite go as planned. Kramer has decided that everyone in the building would be nicer to each other if they knew everyone's name and so puts up photos in the lobby. Soon Jerry has every woman in the building kissing him hello. He tries to stop it but faces dire consequences. George has a problem when he misses an appointment with Wendy and she wants to charge anyways. Jerry gets his parents arguing with his uncle Leo after revealing a family secret.—garykmcd

While walking down the street, Jerry and George meet Elaine and her friend, Wendy (Wendie Malick), who is 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, Elaine scolds him for asking Wendy questions about her work outside her office. They discuss Wendy's old, 1960s-style hairdo that Elaine wishes she would change. Because only the bluntly frank Kramer would dare comment on it to her directly, they plan to introduce him to her.

Later, at Wendy's clinic, George is angry at her because he gets charged for missing his appointment due to her 24-hour cancellation policy.

Kramer reveals a plan to put each tenant's picture and name up in the building's lobby so everybody will know each other by first name. Jerry finds Kramer rummaging for a picture of him, but Jerry reveals that he doesn't like the apartment name idea, so Kramer returns with a Polaroid and takes a surprise photo of Jerry to put up on the wall.

Jerry's Nana (Billye Ree Wallace) calls him to open up a bottle of ketchup. When Jerry goes to her apartment, Uncle Leo (Len Lesser) is also there. Nana mentions something about Leo owing $50 to Jerry's mother, Helen (Liz Sheridan). As it turns out, Nana is referring to an incident from Leo and Helen's childhood. Leo's father had won $1000 at the tracks and gave $100 to Leo and asked him to give $50 to Helen. When Jerry tells his father, Morty, an angry Morty (Barney Martin) calculates what the interest would be on $50 after 50 years, comes to $663.45. Later, Jerry finds out that Uncle Leo put Nana in a nursing home, presumably to "silence" Nana from talking about the $50.

At Jerry's apartment, Elaine arrives with Wendy, and introduces her to Kramer, hoping that he will mention her hair. However, much to Elaine's despair, Kramer loves the haircut, and tells her so.

Since Kramer has placed all of the tenants' photos on the wall in the building lobby, everyone is now greeting each other by first name. Unfortunately for Jerry, he is now getting kissed hello by several of his neighbors, much to his dismay. Having decided that he no longer wants to kiss hello, he begins avoiding their kisses, but is ostracized, his picture is defaced, and nobody wants to talk to him.

Wendy cancels her appointments to go skiing with Elaine, which angers George because she closes her office to do so, canceling his new appointment. Later, upon returning from skiing, Wendy won't drive Elaine all the way back to her apartment due to one-way streets. Elaine is forced to carry her ski equipment the extra way blocks home and injures her arm.

At Wendy's clinic, Elaine is infuriated to hear that Wendy is going to charge her for her treatment, so Elaine finally confronts Wendy about her old-fashioned hairdo.

In the last shot, Kramer is having some tenants over in his apartment. When Jerry stops by, Kramer tells him that he has broken up with Wendy because she changed her hairstyle. He won't allow Jerry in so as not to upset the visiting tenants, who are no longer friendly towards him.

Uncle Leo refuses to pay Helen and Morty as he says they have no proof. Jerry visits Nana at the home & finds that Nana has met an old acquaintance, Buddy. Buddy says he was at the track that day when Leo's dad won $1000 & gave $100 to Leo and asked him to pay Helen $50.
