The toy that blinks its lights at Bart in the 99-cent Store resembles the original Optimus Prime cab-over Semi of the Transformers cartoon from 1984.
The scene where Bestimus Mucho brings several Posibots to life with beams is a parody of this commercial for Microman, a toyline which produced transforming robots that would become the basis for several Transformer characters.
Homer and Ned's cars transform into robots resembling Optimus Prime and Megatron.
It's the Grand Pumpkin, Milhouse is a parody of It's The Great Pumpkin, Charlie Brown. It was supposed to be called, It's the Great Pumpkin, Milhouse, but due to legal reasons, it was renamed to the Grand Pumpkin.
Milhouse's prayer to the Grand Pumpkin is similar to the Nicene Creed.
The dance scene in It's the Grand Pumpkin, Milhouse is a parody of the dance scene in A Charlie Brown Christmas.

The Gay, Lesbian and Straight Education Network, which was in the middle of running a campaign to prevent casual use of the adjective "gay", criticized Nelson Muntz's lyric in the "We Wish You a Merry Christmas" parody, "the Grand Pumpkin's super gay". A spokesperson for the GLSEN said "many people say gay without even realizing what they're saying is bad, we're trying to educate people that this is a term that is hurtful to young people when used in a negative way. The spokesperson added, "Nelson should send an apologetic e-card to Milhouse."
This episode may be considered both a Christmas and a Halloween episode at the same time (if you are watching the Untitled Robot Parody segment of this episode).
When the celebrities in heaven are talking about the people telling about exploiting their images, George Washington and Abraham Lincoln are seen. It would be impossible for Homer to kill them, as they died in the 1700s and 1800s. Maybe Washington found his advertising portrayal offensive.
This episode shows Homer killing Prince by attacking him with his (Prince's) guitar. In real life, the cause of Prince's death was an accidental fentanyl overdose at his Paisley Park home and recording studio in Chanhassen, Minnesota.
This would be the last Treehouse of Horror episode to air on November until 2010 when Treehouse of Horror XXI aired on November seventh.
This is also the last Treehouse of Horror episode to be produced in the 4:3 ratio.
Amber appears in this episode, even though she died two seasons earlier.
If you look closely you can see Krusty's hand flying from the woodchipper, but his hand was nowhere near it.
In the UK, the following scenes are cut from all three sections when aired on Channel 4:
"Untitled Robot Parody": The appearance of the Sex Toy Robot.
"How to Get Ahead in Dead-Vertisting": Krusty getting shredded in the woodchipper, Homer strangling, stabbing, and beating Prince with his own guitar, and Krusty shooting Homer in the head.
"It's The Grand Pumpkin, Milhouse": The Grand Pumpkin puking after learning that pumpkin bread is made of pumpkins (and not bread for pumpkins), The scene where Homer was carving pumpkins and then being eaten after he was found by the Grand Pumpkin, Nelson calling the Grand Pumpkin a racist because he doesn't care that Nelson is going to carve a yellow pumpkin, The Grand Pumpkin scooping the brains out of Skinner's head and Tom Turkey blowing the Grand Pumpkin's brains out by blowing through a cornucopia (along with the Grand Pumpkin's dying words, although with the scene that was cut which involved Homer it might have been done so a plot hole wouldn't have been made at all).
Previous Episode References
The Sex Toy Robot sounds like Andre (the sleazy guy Patty and Selma wanted Marge to date while Homer is in the hospital) from "Homer's Triple Bypass."
"Hungry, Hungry Homer": Homer sleeps on the roof of the house like Snoopy from the Peanuts specials and Bart says, "Good grief."
"Treehouse of Horror XI": A "Treehouse of Horror" story where Homer dies and John Wayne is shown in the afterlife (only in Treehouse of Horror XI, he's in Hell).
"Saddlesore Galactica": Homer is chased by a group of angry people riding on horses (the jockey elves/the dead celebrities). Also, John Lennon's line about eating brains is similar to one of the jockey elves' threats to eat Homer's brain.
"Treehouse of Horror III": A "Treehouse of Horror" story featuring malevolent toys come to life ("Clown Without Pity"/"Untitled Robot Parody").
"Treehouse of Horror VI": The Gracie Films logo didn't have the organ or scream and instead was replaced with a "Philip Glass Homage" jingle of the third segment, whereas, in this episode, it uses the "Peanuts-style" jingle from the same segment, this is shown calmly in the episode.
