History Recap / TheSimpsonsS20E4TreehouseOfHorrorXIX

** In the Transformers parody, Marge managed to convince the two leaders of the robot armies to end their age-old war...[[PacifismBackfire only for them to team up to take over Earth]].

* FantasticRacism [=/=] AtLeastIAdmitIt: The ''Grand'' Pumpkin cares nothing about yellow pumpkins being carved, going as far as to proudly admitting that he and all other pumpkins are racist but orange ones admit their racism.

* BrickJoke: We see Santa's Helper napping on top of his doghouse like Snoopy. In a FreezeFrameBonus, we see that he's flying in a World War I Flying Ace outfit into the night sky.

This year, we have a Transformers parody with robots attacking each other in Springfield, Homer murdering celebrities for fun and profit (mostly profit for the executives who want to use celebrities in their ads), and a lawyer-friendly ''ComicStrip/{{Peanuts}}'' parody featuring a murderous pumpkin.

!! Tropes:

* AccidentalMurder: Homer's murder of Krusty in the second story. He was simply shoving him for upsetting Maggie, but they happened to be near a wood chipper at the time.

* GoneHorriblyWrong: Milhouse's immense belief manages to create both the Grand Pumpkin and Tom Turkey, but unfortunately both of them are driven to KillAllHumans once they respectively learn that their kind gets eaten and/or carved.
* HarmlessVillain: The Grand Pumpkin is ultimately revealed as one. While he terrifies the kids and eats people, he has no working digestive track. When Tom Turkey blows a hole in him, it reveals everyone he ate is fine, just covered in pumpkin juices.

* {{Homage}}: "It's the Grand Pumpkin" Milhouse shows more attention to detail than the other shorts to animate it in the ''Peanuts'' style, with Lisa at one point reciting Sally's iconic "You owe me restitution!"

* LampshadeHanging: In the second story, after the dead celebrities invade the living world, Chief Wiggum is confronted by vocal inspiration Creator/EdwardGRobinson and accused of ripping him off.

* RecordNeedleScratch: An iPod-styled music player actually makes such a sound when Milhouses stops the music (Vince Guaraldi's "Christmas is Coming") at the Halloween party to warn the kids about the Grand Pumpkins' rampage.

* TheUnintelligible: {{Subverted|Trope}}. At first, it seemed the adults in the ''Peanuts'' parody would be this like in the real ''Peanuts'' stories but the only adult sounding like that was Marge while playing the trombone. (In a way, the gag doesn't really work, because Homer had already appeared in full view during the opening sequence, acting like Snoopy.)

* ShoutOut: "How To Get Ahead in Dead-vertising" copies the entire opening sequence of ''Series/MadMen'' for its title.

** "How to Get Ahead in Dead-vertising": All of the deaths listed in the FamilyUnfriendlyDeath entry below are removed (Prince getting stabbed with his guitar, Krusty getting jettisoned into a wood chipper, and Homer getting shot in the head by Krusty).

* OnlySaneWoman: Lisa in "It's the Grand Pumpkin, Milhouse". Aside from her DisproportionateRetribution above, at least she knows that telling a giant talking turkey that people eat turkeys is a bad idea, and tries to cover Bart's mouth when he thoughtlessly does this.

* YeOldeButcheredEnglishe: Tom Turkey talks like this (after all, he also dresses like a Puritan).

** Parodied when Willie offers the Grand Pumpkin some pumpkin seeds. "You roast the unborn?!"

* GoneHorriblyWrong: Milhouse's immense belief manages to create both the Grand Pumpkin and Tom Turkey, but unfortunately both of them are driven to KillAllHumans once they respectively learn that their kind gets eaten and or carved.

** Bart and Milhouse in the ''Peanuts'' parody. First Milhouse feeds the Grand Pumpkin pumpkin bread, then tells him it's made from pumpkins, not ''for'' pumpkins, then he suggests that Tom Turkey could carve the Thanksgiving turkey. when a bewildered Tom asks if they ''eat'' turkeys, Bart proceeds to go into details about stuffing them. Guess what happens.

* WoobieDestroyerOfWorlds: Both the Grand Pumpkin and Tom Turkey if you think about it. They each start off as friendly and heroic, but once they each learn that their kind gets eaten and or carved, they both go on a RoaringRampageOfRevenge.

* TheDeadRiseToAdvertise: The second story's theme has Homer being hired by advertising agencies to kill celebrities so that their likenesses can be used in commercials for free..

* JerkassHasAPoint: Krusty destroying the images of himself in front of a tearful Maggie was cruel, but they ''were'' unlicensed.
