Archer's last exchange with Delaney references the Magnum P.I. episode Did You See the Sunrise? (1982).
Krieger, in attempting to lie to Cyril, awkwardly asserts there are "a lot of Portuguese" in Rhode Island. This is actually somewhat true as Portuguese is the third most common language in Rhode Island after English and Spanish.
The Portuguese written on the card Dr. Krieger makes up for Archer says, "Good morning. I have breast cancer."
Delaney refers to Malory performing a sexual act with beads, which he describes as "just like an SSP Racer". This refers to a line of toys from Kenner dating to the early 1970s. An SSP Racer was powered by a plastic pull cord that was vigorously pulled out from a toy racer car with a characteristic "Zing" buzz.
The rifle Archer uses is a Walther WA2000 and only 176 were ever made.
