When Wallace comes to pick Veronica up after Sheriff Lamb lets her out of prison, Lamb asks Wallace where he has seen him before. Wallace reminds Lamb of their interaction in the pilot episode, in which Lamb told Wallace to "go see the Wizard and ask him for some guts;" when Lamb asks Wallace if he ever did that, Wallace responds, "yeah--he said to let you know you're the only sheriff in America who he considers a true Friend of Dorothy." Although Wallace's response is a continuation of the The Wizard of Oz (1939) theme of the interchange, it is also a reference to the fact that "Friend of Dorothy" is a mid-twentieth-century euphemism for a gay person. Although the term was originally a sub rosa way for gay people (mostly men) to refer to each other without letting straight people know they were discussing homosexuality, it is now fairly well-known among straight people as well (for example, see the "quotes" section for Clueless (1995)).
Creutzfeldt-Jakob Disease is a degenerative neurological disease. It related to, although not caused by, Bovine Spongiform Encephelopathy (BSE), or "mad cow disease."

When Keith comes to visit Veronica in jail, her hand-drawn "tattoo" is briefly visible: it is a cartoon unicorn with a banner reading "Thug Life" over it. "Thug Life" was the name of the hip hop group founded by Tupac Shakur and others; it was also the text of one of his most prominent and famous tattoos. Shakur devised a "backronym" for the term: "The Hate U Give Little Infants Fucks Everybody."
The title of this episode is a pun on Mars Bar chocolate.
