to wreak havoc, and a trip back to the 1938 where Springfield suffers an Alien Invasion
, but the residents don't believe it as they've already been fooled by Orson Welles
' radio broadcast of The War of the Worlds
- Anachronism Stew: The third story takes place in 1938 and portrays Abe as a World War I veteran. When Lenny asks why he insists on calling it "World War One", he answers "You'll see".
- However, given Abe's age he would be likelier to be a Spanish-American War veteran than World War I.
- And You Thought It Was Real: The citizens of Springfield end up mistaking a radio broadcast for a report of an actual alien invasion. Realizing their mistake they vow to never be fooled again.
- It becomes inverted the next day when aliens do actually invade and the entire town, despite plenty of evidence to the contrary, simply believe that they are being tricked again.
- Arson, Murder, and Jaywalking: Krusty's Golem on his deeds in the past:
Golem: I feel so guilty! I've mangled and maimed 37 people and I told a telemarketer I was busy when I wasn't! I'm not a good man.
- Artistic License History: There's quite a number of liberties taken in "The Day the Earth Looked Stupid" when it comes to the War of the Worlds broadcast:
- Most of the scenes involving the town of Springfield listening to the broadcast happened during the middle of the day, when the actual broadcast happened during the evening hours.
- One scene involves a group of school students listening to the broadcast in their classroom, which would have been impossible, as the broadcast happened on a Sunday.
- Homer and Marge, who were listening to the broadcast from the very beginning, actually believed that the fictional news reports of Martians landing in the East Coast was real. Those who were actually listening to the broadcast from the very beginning would have known that this was really an episode of The Mercury Theatre on the Air, with the real paranoia being the result of people who were listening to The Chase and Sanborn Hour tuning into this broadcast while the other program was having a musical segment.
- There was little actual panic among the public; the stories about panic and paranoia were mostly made up by newspapers in their New Media Are Evil campaign against radio.
- Bait-and-Switch Comment: When Homer says he has a job for the Golem, he makes it sound like it'll be something evil. He actually wants the Golem to "open the pickle jar".
- After Skinner gets cut in half by the golem, Superintendent Chalmers bellows "SKINNER!" in his usual tone, then sadly laments "I wish we'd been closer".
- Blatant Lies: One of the aliens tries to justify the invasion by claiming the humans were making mass-disintegration weapons. Even the other alien doesn't believe it.
- Blob Monster: Homer eats a small blob from outer space, and becomes a big blob monster himself.
- The Cameo: One of the Germans that Homer eats during Oktoberfest is Uter!
- Does This Remind You of Anything?:
- The aliens' justification to invade Earth is the expressed belief that humans were creating weapons of mass disintegration. This is lampshaded to the point of being stated outright.
- Plus, the following line is about how the aliens expected to win the "hearts and minds" of humans with the invasion. Except, they mean literally.
- Downer Ending: The third segment has Springfield still in ruins three years after Kang and Kodos took over the town, with the aliens bemoaning that the humans still hate their presence, it's implied that they're all enslaved and dissected and with explosions going off every so often. This isn't helped by the gloomy-sounding instrumental of the closing theme song heard in the credits.
- Evil-Detecting Dog: Blue the dog was able to sense something was wrong about the Mayor's so-called shelter for the homeless. After sniffing it, he ran off in fear as while the Mayor shoved the dog's owner right into the "shelter" which is actually just a roofless facade with hungry Homer behind it.
- Food as Bribe: Chief Wiggum is talked out of arresting the Golem for murdering Principal Skinner by being offered latkes and being told they're pan-fried.
- Golem: Krusty somehow got hold of the Golem of Prague itself.
- Groin Attack: The Golem gives Homer one as ordered by Bart.
- Growling Gut: Heard when Homer is turning into the Blob
- Half the Man He Used to Be: The Golem ends up cutting Principal Skinner in half while using him as a yo-yo.
- I'm a Humanitarian: Blob!Homer gets really, really, hungry.
- Insult to Rocks: Groundskeeper Willie invokes this while getting rid of Skinner's corpse after the Golem is finished with him.
Willie: You'll make better mulch than you did a man.
- Iron Maiden: The opening has Moe stuffed into an iron maiden, with his blood spilling and spelling out the episode's title, which he then immediately lampshades afterwards:
Moe: Oh, look at that, my blood's a genius, fancy Roman numerals and everything.
- I Will Fight Some More Forever: The epilogue shows Kang and Kodos having been driven completely ragged by the fact that humanity still continues to fight after a campaign of conquest that has turned Springfield and possibly the world into a post-apocalyptic wasteland, with their conversation punctuated by the occasional explosion on the background (implied to be human insurgents). All of this combines into a fantastical picture of The War on Terror.
- Jewish Complaining: After a little while enjoying using the Golem as a weapon for assassination and doing cool things with, Bart and Lisa get completely fed up with him because once they allow him to speak all that the Golem does, for hours on end, is to complain.
- Kill the Poor: Mayor Quimby and the town of Springfield reach a compromise with Homer, who has gained an insatiable appetite after becoming The Blob: they keep Homer inside a new "homeless shelter," and any vagrants who enter are eaten by him... In a very twisted way, this is effectively supposed to kill two birds with one stone.
- Literal-Minded: One of the aliens claims to have people's hearts and minds and shows a brain and a heart to prove it.
- Monster Clown: Krusty announces the show is now in HD and steps on camera. It brings out every horrific detail of his face. Needless to say, the kids are terrified.
Krusty: That's right, look at your hero!
- Noodle Incident: Exactly how Krusty obtained the Golem of Prague isn't revealed.
- Production Foreshadowing: Producer Al Jean's gag name in the credits is "Al 'July 27, 2007' Jean", referring to the release date of The Simpsons Movie, which was in production at the time.
- Screw This, I'm Outta Here!: Orson Welles' sound effect guy holds up a "screw you" sign and leaves when Welles announces the aliens are playing the xylophone and bowling by the airport.
- Suddenly Voiced: The Golem was completely mute until Lisa gave him the order to "Speak". Afer that he becomes a neurotic who is constantly complaining and actually feels guilty for his actions.
- Staircase Tumble: A first-person one happens in the Tales from the Crypt-parodying opening sequence.
- Take That!:
- When the blob tries to escape from Homer's body.
Homer: If I can keep down Arby's, I can keep down you!
- Krusty says that, as a defender of the Jewish people, the Golem is like Alan Dershowitz but with a conscience. Krusty says he's just joking about Alan.
- Talking the Monster to Death: Marge is the only one who is able to convince Blob Homer to stop eating everyone, but has mixed results: Homer in the end agrees to only eat the homeless from now on.
- Tempting Fate: Done twice by Homer regarding the blob. When Lisa suggests it might be an intelligent being, Homer asks why it doesn't try to escape his mouth. The blob tries so. After Marge berates Homer for eating something without knowing which galaxy it came from, he says he ate it and it's over. The blob then makes another escape attempt.
- Too Spicy for Yog-Sothoth: Inverted. The alien blob twice tries to escape Homer's innards after he eats it, and twice Homer prevents it.
