Malory makes a remark about Lana's "huge, Johnny Bench-ian fingers". Johnny Bench was a catcher for the Cincinnati Reds baseball team. He had famously huge hands and long fingers; he could hold 7 standard baseballs in one hand. A photograph of him performing this feat became famous during his lifetime.
References the scene in The Deer Hunter (1978) where Robert De Niro's character tricks his Vietnamese captors, who are forcing him to play Russian Roulette, to put extra rounds in the gun. He then uses the extra rounds to kill his captors and escape.
When Archer stumbles upon Elke's compact with the video screen as Major Jakov tries to contact her, at one point Jakov says, "What is the frequency?", to which Archer quizzically replies "Kenneth?" This is a reference to the song "What's the Frequency, Kenneth?" by R.E.M.
During dinner, Malory Archer states that if she is found with another dead body, her neighbor Trudy Beekman will have her in front of the Homeowners Association again, after which Archer remarks that she doesn't get along with her neighbors anywhere. This is a reference to Arrested Development (2003), where Lucille Bluth, also played by Jessica Walter, has a long-running rivalry with her neighbor Lucille Austero, a.k.a. "Lucille 2".
First instance of the "Phrasing!" running gag.
