In the background of Sidney's boss's office there's a picture of a buff God in a bikini. This is the second episode that has that picture, the first being "Rodger Codger."
The woman behind Roger at the convenience store is the liquor store cashier that Roger claimed to have a crush on in "The Magnificent Steven." And the woman behind the counter is the owner of the teddy bear store in "American Dream Factory."
Goof: When McCreary is reading the first line from the book of Genesis, his Bible is opened to the middle. It should be opened to approximately the first page, as Genesis is the first book in The Bible.
Roger is seen in his Jamaican Rastafarian disguise from "Francine's Flashback" at the end of the opening credits this week. Having Roger appear differently each week may be a replacement for the topical newspaper headline shown in the first three seasons.
When Roger is waiting in line at the mini mart he draws a moustache on the covergirl of a Modern Bride magazine while humming the German national anthem "Deutschland Über Alles".
Sidney's look and dialect are alluding James Stewart. Also, in Sidney's room there's a poster for the 1953 movie The Glenn Miller Story (starring Stewart), and his alarm plays the 1940 song "Pennsylvania 6-5000" by Glenn Miller.
J. C. Penney
The store where Sidney's girlfriend works is called C.J Neppey, a parody of J. C. Penney, which is a low-range chain of American department stores based in Plano, Texas.
Little Miss Sunshine
When the hitman's daughter begins crying, he calls her "Little Miss Fusshine", in reference to the 2006 film Little Miss Sunshine.
Fight Club
Roger's dilemma recalls that of the nameless protagonist in Chuck Palahniuk's Fight Club, who learns that he unwittingly harbors a psychotic, amoral second personality named Tyler Durden, whom he "meets" on a plane ride. He "kills" Tyler in the end, as Roger does his other self. Ironically, Sydney Huffman is just the opposite of Tyler (and Roger): a gentle, sober, and morally upright fellow.
