seven from the seventh season, was released on a three-disc DVD set in the United States on June 15, 2010. The DVDs included brief audio commentaries by Seth MacFarlane and various other crew and cast members from several episodes, a collection of deleted scenes, a special mini-feature that discussed the process behind animating "Road to the Multiverse", and a mini-feature entitled Family Guy Karaoke. The set also includes a reprint of the script for the episode. Cultural references Peter, who tries to shave Quagmire's cat in the episode, ends up killing it and cutting it six times because of the legend of cats having nine lives. As he is arresting Brian, one of the police officers states that he will not release him since he is a "family guy". In their campaign, Brian and Stewie perform their musical number, '"A Bag o' Weed", to the tune of "Me Ol' Bamboo" as featured in the film Chitty Chitty Bang Bang. During the song, a picture of Woody Harrelson (who also wanted marijuana legalized) is shown. Towards the end of the musical number, Shaggy from the television show Scooby-Doo can be seen among the crowd, referencing a number of jokes about his stoned-like demeanor. After cannabis is legalized, its effects include phenomenal ratings for Doctor Who. Peter then tries to set up a cutaway joke but can't due to being high, and ends up listing the names of celebrities whom he does not like in a text crawl. While helping out with Carter's smear campaign, Peter comes up with an advertisement that involves Adolf Hitler claiming that the Holocaust was started by smoking cannabis. The campaign is then dropped after Carter informs Peter that Fox News holds Hitler's image rights and they cannot smear it. He later tries to film a new advertisement which informs that unlike the events of the film Harold & Kumar Go to White Castle, he made it there earlier since he was not stoned. He then says Neil Patrick Harris was cast on How I Met Your Mother based on his work in that film, and brings up a point that confuses him: since Josh Radnor is already an adult, why is the narrator of the show voiced by Bob Saget? Carter later tells Brian that he will release his novel with an Oprah's Book Club induction. The crudely animated cutaway featuring a man smoking a joint
