Just before cutting to commercial, Pam pops one of her cocaine "mints" and smiles, after which a tiny sparkle appears in the corner of her mouth. This is a reference to a series of commercials for Mentos from the 1980s and '90s, where it was marketed as "The Freshmaker". The packaging for Pam's "mints" even resembles the packaging for Mentos from that time period.
Archer berating Pam to not make fun of Messina is a nod to musician Jim Messina, who was a member of the folk rock group Buffalo Springfield, a founding member of the country rock band Poco (as noted by Archer), and was one-half of the soft-rock duo Loggins & Messina, along with Kenny Loggins.
Despite the song "Danger Zone" being a running gag, this is the only time in the series it is actually played.
When Archer comments that Kenny Loggins' briefcase holds "either plutonium or a human soul" this possibly is a reference to the rumor that the suitcase from Pulp Fiction (1994) contains Marsellus Wallace's soul due to various other indicators, such as the suitcase glowing when opened.
When Archer falls over backwards and shatters the jug he was using as a musical instrument, he says, "I'm 'a plant a red fern for ya, jug." imitating a hillbilly accent. This is a reference to the 1961 novel "Where the Red Fern Grows" by Wilson Rawls. The novel is set in the Ozark Mountains and tells of a boy whose dogs die, and a red fern grows over the grave.
