Pinkeye/Trivia

Trivia

 * In this episode as Liane is singing "I'm gonna decorate the house with lots of creepy crawly things" she's hanging up a picture of Former U.S. President Richard Nixon.
 * When Kenny attacks the old woman, his mouth is shown for when he is biting her arm. This was the first time his mouth was ever shown.
 * This episode features the news reporter Midget Wearing Bikini. He returned in the same role in South Park: Bigger, Longer & Uncut.
 * In the scene where Chef is watching the news in his house, a poster of Isaac Hayes (the voice of Chef) can be seen.
 * In the final scene, a tombstone statue of Orgazmo can be seen in the background.
 * Mr. Garrison's Halloween costume looks very similar the way he would look as Janet Garrison eight seasons later.
 * The entire Zombie aspect of this episode is an homage to Return of the Living Dead. Everything from the doctors describing the zombies' symptoms to the emergency hotline number on the "embalming fluid" container is a throwback to the plotline of Return of the Living Dead.
 * The "Russian" spoken by the cosmonauts on Mir is in fact vaguely Russian-sounding gibberish. Similarly, Hitler's speech in the video shown to Cartman is a meaningless string of actual German (and some made-up) words. One section sounds vaguely like German for "you have lovely breasts," although this may be unintentional. When Cartman imagines himself as Hitler, his speech is actually made up of backwards English phrases (including "You guys" and "Seriously, you don't know shit") and some more made-up German, ending with the phrase "God-damn it!"
 * This is the episode in-which Kenny dies the most (three times, which would later be tied in "Coon vs. Coon & Friends").
 * After Kenny dies and becomes a zombie he never made any attempts to eat Stan, Kyle or Cartman, not even when the boys insult him but was quick enough to jump at Clyde and the people answering the doors where the boys went trick-or-treating. Funny enough right after Wendy becomes a zombie she didn't show the same kind of commitment.
 * In a later series on another Halloween episode, Wendy won another costume contest with her Chewbacca costume.
 * After getting unhappy with Cartman's Hitler outfit, Principal Victoria gives him a new costume which ends up looking like the cloak a KKK member wears, but only Chef seems to notice it (and even runs from him at first).
 * When knocking on one house, some members of the KKK answer the door and Cartman replies Hey! They're all dressed up like ghosts too!, assuming he didn't know who or what the KKK were then.
 * When the Midget in a Bikini is reporting on top of a building you can see Jimbo Kern and Ned with a rocket launcher.
 * This episode marks the first appearance of Principal Victoria.

References to Popular Culture

 * The space station that de-orbits and crashes on Kenny at the beginning of the episode is the space station Mir.

At the time this episode originally aired, the Mir space station had two accidents. In February 1996 the station had a fire on board, and later that year June it was involved with a collision with an unmanned space craft.

 * Mr. Garrison is dressed up like Marilyn Monroe, who was a famous American actress, model, and sex symbol before her death in 1962.
 * Cartman mistakenly believes that Wookies like Chewbacca live on the Endor. In Star Wars mythology the teddy-bear like Ewoks live on the moon known as Endor. Wookies live on the planet Kashyyyk.

The special is centered around Chewbacca and his family, who are depicted as living in a tree-house similar to those built by the Ewoks.
 * Mr. Garrison teachers the class about "horror writer" Jackie Collins.

 * The children's Halloween costume contest is judged by actress Tina Yothers, who was most well known for her role of Jennifer Keaton on the sitcom Family Ties.

 * Mr. Garrison mistakenly believes the zombified corpse of Kenny to be a costume patterned after Edward James Olmos, an actor who's most well known for his role of Gaff in the film Blade Runner.
 * There is a poster of naked women on the wall in Chef's house, this poster looks very similar to one featured in Stanley Kubrick's 1980 adaptation of the Stephen King novel The Shining.

 * When once again making fun of Stan's costume, Cartman calls him Pippi Longstocking, a fictional character created by Swedish author Astrid Lindgren.

 * The fat man handing out candy is ironically wearing a shirt that says "Let's Get Physical". The phrase is from the song Physical a 1981 song written by Steve Kipner and Terry Shaddick and performed by Olivia Newton-John. The music video for the song featured a lot of over-weight men exercising.

 * At the end of the song when Chef pulls open his shirt and shouts "OOOOOOOOH!" Is another reference to Michael Jackson, however was something that Jackson did in the music video for his 1991 song Black or White. The end of the video featured Jackson doing this same move.
 * According to the Worcestershire sauce hot-line, to cure people of being zombies you have to kill the original zombie. This is actually more common with Vampire mythology as opposed to zombie lore.
