For the series' 100th episode, Jerry Seinfeld hosts a one hour retrospective with clips from previous episodes: the idea for a show about nothing; the smelly car; the puffy shirt; the astronaut pen; Jerry's hair; George's lack of hair; Mulva; Jerry's virgin girlfriend; the Hernandez incident; the outing; the masters of their domain; the bubble boy - are only a few of the episodes included.

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. Meanwhile, Elaine's friend who is a chiropractor skips out on George's appointment and goes skiing instead, and they have a hard time telling her about her dated hairdo.
