For the end credits, a “medieval” version of the theme song is heard.
Chris watches a rerun of the 1970s game show The Match Game with host Gene Rayburn reading this question to the panel: “Forgetful Freddy was so forgetful, when he tried to remember someone’s name he drew a blank,” parodying the show’s use of fill-in-the-blank queries. Brett Somers appears on The Match Game as one of the panelists. Dan Palladino notes in the episode commentary that they made a mistake in her placement, shifting her to the side from her traditional top center seat.
To impress Mr. Weed, the Chris, Stewie and Meg sing "So Long, Farewell" from the musical The Sound of Music. According to Seth MacFarlane on the DVD commentary track for this episode, the estate of Rodgers and Hammerstein asked that an unrelated “fart joke” be removed from the script before approving the use of the song "So Long, Farewell".
Also in the commentary, MacFarlane comments that the censors would not allow them to use the term “half and half” in the scene where Peter tries out prostitution as a job. The censors did allow the term “Cleveland steamer”, which MacFarlane cheerfully admitted is a much more vile, if lesser known, concept.
