Jerry offends a distant relative as he claims he hates "anyone who ever had a pony when growing up". Soon said relative passes away and Jerry feels guilty about it. Worse thing is that the funeral is scheduled just before the softball tournament final, where Jerry's team will be playing.
* TheBet: Kramer plans to replace his flat's furniture with "levels". Jerry, knowing beforehand that he won't actually do it makes a bet about it. Kramer then declares the bet invalid as soon he backs out of his project.
* CharacterizationMarchesOn: This is the first episode with Uncle Leo, and while he's still an annoying pest towards Jerry, he behaves more stern and no-nonsense here, than in subsequent episodes.
* DeadpanSnarker: Elaine begins to show some signs of this:
--> "Funerals always make me think about my own mortality and how I'm actually going to die someday. Me, dead. Imagine that!"
* TheGambler: Kramer's gambling habit is introduced here.
* TheGhost: The first we hear of Jerry's unseen cousin Jeffrey.
* GrowingTheBeard: Many critics, including the New York Times have called this episode a turning point in the show's history.
* TheOtherDarrin: With this episode, Barney Martin takes over the role of Morty Seinfeld.
* OutOfFocus: George doesn't really have a storyline here. His only real purpose in this episode is to try and talk Jerry out of attending Manya's funeral so he can take part in a sporting event. In fact George doesn't appear until over halfway through the episode!
** Kramer doesn't have much to do either, except for planning to revamp his pad.
* ValuesDissonance: An in-universe example. Manya feels extremely offended by Jerry's remark about ponies. But, as Jerry lampshades it, ponies are like compact cars in Poland, while in New York, they are more associated with snooty kids with Dutch surnames.
