In the montage of Jim's previous costumes, Jim is shown with the word "book" written on his face as a reference to being Facebook. This clip is taken from the original opening of Koi Pond (2009), which was later changed after viewer complaints of Michael fake committing suicide.
Despite their characters having a rivalry and an awkward relationship in the show, John Krasinski has confessed that Timothy Olyphant was one of his favorite people to make a guest appearance on the show and said he hugely enjoyed working with him.
The mini horse that Dwight brings to the office during the cold open also played Lil' Sebastian in the NBC sitcom Parks and Recreation (2009).
In Koi Pond (2009), Dwight and Michael make fun of Jim, saying he looks like Popeye's wife. In this episode, Jim and Pam dress up like Popeye and Popeye's wife.
Five people change outfits during the episode. Kelly changes into a colorful polka dotted dress, Oscar changes into his "rational consumer" outfit, Michael into a Darryl costume then back to Macgruber, Angela changes into a nurse costume, and Jim changes into a Popeye costume.
