The Nielsen ratings for this episode were so low that the show was put on hiatus and considered for cancellation. It returned two months later.
This episode was quickly written to replace an episode titled "The Bet," which was never filmed. The script by Larry Charles had Jerry betting Elaine $100 that she will not buy a gun. Elaine ends up buying a gun from a friend of Kramer's. The script featured a scene in which Elaine points the gun to her head and asks, "Where do you want it, Jerry? The Kennedy? The McKinley?" This is a reference to two assassinated US presidents, John F. Kennedy and William McKinley, both of whom died of gunshot wounds. After reading the scene, Julia Louis-Dreyfus turned to Jason Alexander and said "I'm not doing this," and the episode was scrapped.
Larry David once attempted to replace an answering-phone tape with a blank one in order to remove an embarrassing message he left.
Carol says she recognizes Jerry from The Tonight Show with Jay Leno (1992). This is the earliest reference to Jerry being a celebrity within the universe of the show.
This is the last time that Jerry's apartment is 3A. After this, it's always 5A.
