A sign in the background of the ice cream shop (above Archer's head) has the words "Poovey Farms" written upside down. This is a reference to Pam's family's dairy farm in the original Archer storyline.
Mallory has a conversation with Krieger (currently an android) about dreaming and electric sheep. The Philip K. Dick story "Do Androids Dream of Electric Sheep" is the basis for the movie Blade Runner (1982).
