----
* 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-nonsese here, than in subsequent episodes.
* 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 a family member's funeral so he can take part in a sporting event. In fact George doesn't appear until over halfway through the episode!
* TheGambler: Kramer's gambling habit is introduced here.
* TheGhost: The first we hear of Jerry's unseen cousin Jeffrey.
* TheOtherDarrin: With this episode, Barney Martin takes over the role of Morty Seinfeld.
