Kramer (Michael Richards) remarked at the end of the episode: "Boy, I really liked the two of you much better when you weren't a couple." It was a poke at NBC who desperately wanted Elaine (Julia Louis-Dreyfus) & Seinfeld together. Jerry Seinfeld and Larry David were against the idea of Jerry and Elaine being in a 'will-they, won't-they' relationship.
Larry David was nominated for an Emmy award in the Outstanding Writing in a Comedy Series category for this episode.
This episode marks the first appearance of Siobhan Fallon Hogan, Elaine's (Julia Louis-Dreyfus) roommate. Tina appears two more times during the series: in season three's The Truth (1991) and in season five's The Opposite (1994).
"The Helsinki Formula" is not an actual movie, but an infomercial from the 1980s that featured Robert Vaughn promoting a hair-growth product, which was later proven to be fraudulent.
