The first network appearance of Jerry Stiller as Frank Costanza. Later, for continuity sake in syndication, Jerry Stiller re-shot the scenes featuring his character in the previous season four episode Seinfeld: The Handicap Spot (1993).
There must have only been one puffy shirt made for this episode since not both of the homeless men in the final scene are wearing them. The man Jerry (Jerry Seinfeld) gives money to is, but the other one is only wearing a loose-fitting collarless shirt that is only similar.
This episode's plot is a little different to others, in that the story mainly revolves around Jerry (Jerry Seinfeld) and George (Jason Alexander). Elaine (Julia Louis-Dreyfus) and Kramer (Michael Richards) are only supporting characters in this episode, whereas most other episodes contain a story line for each main character.
The trivia items below may give away important plot points.
In this episode George (Jason Alexander) tells Jerry (Jerry Seinfeld) that his mother, Estelle (Estelle Harris), has never laughed, ever. Later in the episode the point is proven when Jerry attempts to tell her a joke and she's not interested. But in episode 7.15, Seinfeld: The Shower Head (1996), Estelle laughs at Jerry's joke: "Actually I'm drunk." Maybe this is her first time laughing ever.
