This is the first appearance of Julia Louis-Dreyfus as Elaine. Although this is the second episode to air, it was the third episode to be produced. It was decided that it should air second because it provided background information about Elaine and her relationship with Jerry (Jerry Seinfeld).
Philip Sterling was originally cast as Jerry's father, Morty, but was replaced with Philip Bruns. Bruns was later replaced in the second season by Barney Martin because it was decided the character should be more cranky. When the show went into syndication, Larry David wanted to reshoot Bruns' scenes with Martin but decided against the idea because the differences in the cast's ages would be noticeable.
The plot is based on a real-life experience of Larry David. The names of the people in the the law firm "Sagman, Bennett, Robbins, Oppenheim and Taft" are friends David made at college.
This episode contains the first mention of George's (Jason Alexander) favorite alias/fictional name "Art Vandelay."
Jerry's (Jerry Seinfeld) apartment is set up as a studio, and Jerry refers to the fold out bed as his bed. The door to Jerry's bedroom does not appear until Season 2. In Season 1, there is just a blank wall next to the bookshelf in the bathroom hallway.
