When George (Jason Alexander) is ironing his pants talking to Elaine (Julia Louis-Dreyfus) and Anna (Rebecca McFarland) on speaker phone, you can see George has hamsters. There is a little white hamster climbing through a colorful hamster tube behind him.
According to Julia Louis-Dreyfus, the key to the comedy in her dancing was to look as ridiculous as possible while keeping her face full of confidence and thorough enjoyment. It was important to her to look like a fool but also be funny. In this sense, in spite of the fact that she was deliberately dancing poorly, she was going for a feeling of humiliation, as she wanted people to laugh at her more than with her.
In the opening scene of this episode, Jerry (Jerry Seinfeld) and Kramer (Michael Richards) are discussing which side of a sidewalk is safer. Jerry tells Kramer that by walking on the inside of the sidewalk, an air conditioner could hit you if it fell out. In episode 5.3 Seinfeld: The Glasses (1993), Jerry's AC unit falls out of its window to the sidewalk below, injuring a dog.
Elaine's (Julia Louis-Dreyfus) dancing in this episode was inspired by the Saturday Night Live (1975) boss Lorne Michaels. Seinfeld writer, Spike Feresten, started his career as a receptionist at SNL and has said that at a SNL after-party, he saw Michaels dance "as if he'd never seen another human being dance before" and that he "heaved and gyrated to a rhythm only he could feel."
Elaine (Julia Louis-Dreyfus) makes the following toast during a Peterman company party: "Here's to those who wish us well and those who don't can go to hell." This was inspired by episode writer Spike Feresten's grandmother, who used to make the exact same declaration at his family Thanksgiving dinner every year.
One of the fictional movie titles used in this episode was "Death Blow." In 1995 an aspiring filmmaker took out a full-page ad in Variety, seeking a $100,000 investment in his screenplay. Episode writer Spike Feresten liked the title and decided to use it for this episode.
