|Treehouse of Horror III||
- The scene where Homer gives his warning to the audience is similar to the Marge's warning in the first and second Treehouse of Horror.
- Homer walking onto stage and saying 'Good Evening' is a parody of Alfred Hitchcock, who frequently introduced his TV series in this manner.
- It is the first episode in the series of Treehouse of Horror episodes to have a zombie-related segment. The second is "The Fright to Creep and Scare Harms" in "Treehouse of Horror XIII".
- In segment 'Clown Without Pity' the Springfield children are dressed up in their Halloween costumes, Bart appears in 'A Clockwork Orange' costume dress as 'Alex DeLarge'.
- After seeing Homer run naked through the kitchen, Patty declares that she just lost the last lingering thread to her heterosexuality. 12 seasons later, the episode "There's Something About Marrying" reveals that Patty is a lesbian (despite that she and Selma have a crush on MacGyver) and always knew that she was gay ever since she was a child.
- The names used in Bart's spell book:
- Cullen, Rayburn, Narz, Trebek (last names of game show hosts)
- Zabar, Kresge, Caldor, Walmart (names of inexpensive department stores, with Zabar and WalMart being the only ones as of 2012 still in business, though Kresge is now known as Kmart)
- Kojak, Mannix, Banachek, Danno (names of 1970s TV detectives)
- Trojan, Ramses, Magnum, Sheik (brand names of condoms)
- Costumes at the Halloween party:
- Homer - Julius Caesar (until his toga rips on a nail)
- Bart - Alex DeLarge from A Clockwork Orange
- Lisa - Statue of Liberty
- Marge - Cleopatra
- Milhouse - Radioactive Man
- Nelson - Pirate
- Martin - Calliope, the Muse of heroic poetry
- Janey - Princess
- Lewis - Frankenstein
- Richard - Scratchy
- Becky - Arabian Princess
- Wendell - Astronaut
- The title on the Shop of Evil is "Our one stop evil shop".
- In "King Homer", King Homer eats Lenny, Smithers, Shirley Temple and Clancy Bouvier.
- King Homer climbs only up to the third floor and then faints, due to exhaustion.
- Snowball I lived in years 1988 - 1990.
- Springfield Pet Cemetery appears in the series for the first time.
- This is the second Treehouse of Horror to have the cast and crew's names changed due to Halloween e.g. Bat Groening. The first was in the Treehouse of Horror II.
- This is the final time where the Gracie Films logo in a Halloween special does not have the scream.
- Kang and Kodos' appearance is recycled from the previous "Treehouse of Horror" without the human peace symbol.
- This is the second episode to have characters telling scary stories, the first being Treehouse of Horror.
- The name "Clown without Pity" is a take from the song "Town without Pity."
- The first two segments end similarly with a "Love American Style" ending.
- Dial "Z" for Zombies is the first of 3 zombie segments in Treehouse of Horror.
- The Krusty Doll is said to be a parody of Twilight Zone's "Living Doll", and the Child's Play movies.
- In the Alfred Hitchcock opening, Homer is fatter than the silhouette.
- In the segment "Clown Without Pity", the evil Krusty doll pulls a butcher knife out of nowhere, much like Chucky does in the 1988 horror " Child's Play", when he is fighting against the detective.
- In the scene where Bart attempts to resurrect Snowball I, human zombies arise from around them, despite them being in the pet cemetery. Though some citizens might be cheap and classify their recently deceased loved ones as pets (or the spell Bart chanted was meant to resurrect human zombies and not animals).
- Snowball I is shown as black, but "Lisa's Sax" reveals that Snowball I was a white cat.
- Homer's toga was ripped off when he came down the stairs ("Behold, mighty Caesar! In all his glory!"), but when he ruins the evil witch game by eating the food used as the witch's body parts, Homer is in his normal clothes (white shirt and blue pants). Then when Homer tells his crummy ghost story when the show comes back from commercial break, he's back in his toga.
- In "King Homer," the spinning newspaper that announced Marge marrying King Homer had Woody Allen's birthday as a sub-story, but when the spinning newspaper is shown in full, the Woody Allen birthday story is replaced with Dick Cavett (and both stories have pictures of what each man looks like as an adult, despite that they were just born). This is most likely a deliberate gag.
- In "Clown Without Pity" when Homer yells, "The doll is trying to kill me, and the toaster's been laughing at me!", his mouth doesn't move. Also: the kitchen table is gone.
- Marge finds the customer service number for the Krusty doll on a box, despite that Homer bought the Krusty doll at a curious shop owned by a strange Chinese man and it clearly wasn't in a box when he bought it.
- Baby's First Pop-Up Book should, technically, be 52 pages, since there are two pages for each letter.
- In "Clown Without Pity" when Homer is buying the Krusty doll, it doesn't have a box, however when Bart opens the present, it's in the box.
- In the ending of Dial Z For Zombies, the securiy guard to the right of Mayor Quimby have a dark skin. In the next shot, his skin is yellow.
- The first segment, 'Clown Without Pity' is an overall spoof of the Twilight Zone episode, Living Doll. Coincidentally, Telly Savalas (who is also bald) plays the father in the Twilight Zone original.
- The hold music when Marge calls to complain about the Krusty Doll is "Everybody Loves a Clown" by Gary Lewis and the Playboys.
- Homer sings the Oscar Mayer song only with his first name in place of the O-S-C-A-R and the M-A-Y-E-R.
- 'King Homer' is obviously a parody of King Kong.
- The ad above the one Marge applies for in 'King Homer' is part of the chorus of "Escape (The Pina Colada Song)" by Rupert Holmes.
- The chief of Ape Island shouts "Mosi Tatupu", which is actually the name of an NFL running back who played for the New England Patriots and Los Angeles Rams from 1978 to 1991.
- Shirley Temple is seen dancing and singing before Homer eats her.
- Ape Island is a spoof of Skull Island.
- The Springfield Shopper's November 19, 1936 issue includes an article "Dick Cavett Born." Cavett was actually born on that exact day.
- The title 'Dial Z for Zombies' is a parodic of the title 'Dial M for Murder.'
- One of the books Bart picks out when told to redo his book report is "Find Waldo Yet Again," a spoof of the Where's Waldo (renamed Where's Wally in the UK) picture book series.
- The Necronomicon Bart finds spoofs annual Time Life Magazine endorsed releases of historic and culturally significant media.
- In the Pet Cemetery, there are 3 tombstones that read "Fish Police", "Capitol Critters", and "Family Dog" respectively. This pokes fun of 3 animated shows of the same name that were short-lived.
- When Bart raises the dead, he's wearing a Michael Jackson record on his head (coincidentally, it's the Thriller album).
- When Bart makes the dead raising chants, some of the names he utters include (Alex) Trebek and Wal-Mart. He then mentions the names of famous TV detectives - Kojak, Mannix, Banacek and Dano - in the spell that turns Lisa into a snail. And when turning Lisa back into human form and getting rid of the zombies, he mentions condom brands - Trojan, Ramses, Magnum and Sheik.
- Homer kills the following famous zombies: George Washington, Albert Einstein, and William Shakespeare, each with a witty remark.
