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.

George refuses to give anyone his secret code (BOSCO). Kramer buys a police scanner. Jerry does a series of ads for Leapin' Larry's Appliance Store. Elaine has dinner with J. Peterman but after she and Jerry bail on the dinner, George is stuck to dine with Peterman. George spills his secret code to Peterman's dying mother and gets in trouble for it.

It's finally time for George and Susan's wedding. George doesn't think he can go through with the wedding. But when Susan puts George in charge of the wedding invitations, George gets the cheapest ones in the lot, knowing that the glue for the envelopes is cheap. Unfortunately for Susan, the glue is also toxic and licking the envelopes has fatal consequences. Meanwhile, Jerry courts a woman just like him named Jeannie Steinman and holds up his end of George's "pact" (see episode "The Engagement").
