This episode won Michael Richards his first of three Primetime Emmy Awards for Outstanding Supporting Actor in a Comedy Series.
In "The Junior Mint" George (Jason Alexander) invests in a triangular sculpture thinking its artist is on the brink of death and once he has expired the value of the sculpture will automatically increase. However, the artist makes a startling recovery and George is stuck with the piece. In later episodes the statue can be seen in different places throughout George's apartment, and, perhaps as a inside joke, so too can other triangular motifs (i.e. a baseball pennant).
When George comes to Jerry's apartment and introduces himself to Delores he's carrying several video cassettes. The one on the top is Pretty Woman (1990), in which Jason Alexander played a supporting role.
The production code for this episode (The Junior Mint) is 421 while the production code for The Handicap Spot (1993) is 420, even though The Handicap Spot aired two weeks after The Junior Mint. Because of this, in The Handicap Spot, Jerry (Jerry Seinfeld) mentions to George (Jason Alexander) that he's thinking of getting a yo-yo, but is actually seen playing with it two episodes earlier while in the hospital room in The Junior Mint.
