Jerry's girlfriend Keri, played by Jennette Robbins, who says his pants are "nice" at Joe Mayo's party, was in a Dockers commercial in the '90s, where she's on a subway, sees a guy, gets separated from him, and mouths the words, "nice pants," as the train pulls away.
The real Joe Mayo is a Seinfeld crew member and is listed as a "Utility" person in the credits of the previous episode, but is not included as crew in this episode, which includes a character named Joe Mayo (played by Pat Finn). The crew member however makes a cameo in this episode. He's the guy with a mustache who gets scolded by Puddy (Patrick Warburton).
Elaine says Puddy is "strutting around like he's Stein Eriksen." Stein Eriksen was an alpine ski racer and Olympic gold medalist from Norway.
The working title of this episode was "The Man Fur."
There is no listed credited actress for Svetlana (Silvio's wife) and it's been speculated that there may have been some controversy surrounding her inclusion in the credits and the series paperwork. Though she has no dialogue and non speaking roles are often not credited.
