First Aired - 2/5/1995
After unleashing an unflattering balloon caricature of Principal Skinner, Bart is forced to help Skinner with his early-morning astronomy...and Bart fooling around with the telescope leads to the discovery of a comet that's on a collision course with Springfield.
- Achievements in Ignorance: Skinner has been at his astronomy for years, makes very calculated and precise adjustments with his telescope with the hope of finding something interesting, and has ultimately turned up nothing. Bart screws around with the telescope for a few seconds, spins it around haphazardly, and discovers a comet.
- Apocalypse How: Class 0, as the comet's potential destruction seems to be limited to just Springfield.
- Bait-and-Switch: Ned finds all of Springfield right outside his bomb shelter, glaring at him and in some cases carrying weapons. Moe angrily states they want to be in the shelter themselves, but Ned tells them there's no space. So Moe just calmly announces they'll all "go off and die, then," and everyone turns to leave.
- Big "NO!": Skinner unleashes four of them over the course of the episode.
- Brick Joke: A running one involving the "Big Butt Skinner" balloon.
- Butt-Monkey: Moe's Bar doesn't end up doing well on either projected devastation.
- Chekhov's Gunman: As Professor Frink starts his presentation, a man frantically yells "QUIT STALLING! WHAT'S THE PLAN!?!" That same man appears later that season in "The PTA Disbands," yelling "The PTA has disbanded!" and jumping out a window before being informed that the PTA did not disband, jumping back through that window.
- Colony Drop: The Bart Simpson Comet turns out to be on a direct collision course with Springfield.
- Comically Missing the Point: This exchange between Bart and Lisa, when they realise the comet is approaching Springfield:Lisa: Don't you realize what's happening, Bart? Your comet is gonna collide with the earth and every living thing in its path will be killed.
Bart: I knew you'd try to find something wrong with my comet, Lisa. You've always been petty and small, right from the beginning.
- The Cuckoolander Was Right: Early on, Homer shrugs off the comet's perceived threat, claiming that it will burn up in the atmosphere and end up "no bigger than a chihuahua's head." That's exactly what happens, complete with a nearby chihuahua for comparison.Bart: What's really amazing is that this is exactly what Dad said would happen.
Lisa: Yeah, Dad was right.
Homer: I know, kids... I'm scared too... (the family hugs together, terrified)
- Democracy Is Bad: The Congress is about to pass a bill on the evacuation of Springfield from the comet, but then the bill has a pornography rider attached to it and is promptly struck down. This leads Kent Brockman to declare: "I've said it before, and I'll say it again: democracy simply doesn't work."
- Description Cut: This scene:Homer: It's times like these I wish I were a religious man.
Reverend Lovejoy: It's all over, people! We don't have a prayer!
- Dirty Coward: The whole of Springfield becomes this when they unanimously decide to kick Ned out of his own bomb shelter. At first, not even his wife steps forward for him, but Ned being Ned, he leaves without argument, calmly singing to himself; after trying desperately not to listen, Homer (the one who suggested it) has a Heel Realisation and leaves so Ned doesn't have to face death alone, promptly followed by everyone else.
- Empathic Environment: As Skinner recounts his story to Bart of how his astrological discovery was reported by another school principal before him, a large cloud briefly passes over the moon and darkens the night as Skinner proceeds to growl ominously that he 'got back at him, though; him and that little boy of his'. Then the cloud passes and Skinner returns to his previously upbeat, cheerful manner.
- Epic Fail:
- A figter pilot launched a missile that somehow hits his wingman, and another on himself.
- The missile made to intercept the comet not only doesn't hits the comet but it comes crashing down on the only bridge that leads out of town, sealing it off.
- The endless barrage of people attempting a Ramp Jump to get over the bridge's hole and failing.
- Failed a Spot Check: A pair of fighter jets somehow mistaken an angry Scotsman as an Iraqi fighter jet.
- Freeze-Frame Bonus:
- Kent's "the following people are gay" list consists of Simpsons staff members.
- When the whole town crowds into Ned's bomb shelter, you can briefly see Waldo the first time everyone is shown crowded in.
- Gilligan Cut: When the only bridge out of town is blown up:Lisa: We're doomed!
Homer: It's times like this I wish I were a religious man.
Lovejoy: (running through the streets) It's all over, people! We don't have a prayer! Aaaahh!!!
- Green Aesop: Inverted. The town is saved only because the clouds of pollution high above it thickened the atmosphere to the necessary levels to destroy the comet. Lisa even lampshades this while pointing out that Homer was right in his assumption.
- HeelFace Turn: Downplayed example with Homer. He's the first to exit the bomb shelter since he can't in his good conscience let Ned die alone, but conveniently forgets that he was the one who booted him out in the first place and called him useless.
- The final act has several to The Twilight Zone episode "The Monsters Are Due on Maple Street". There are even stronger parallels to another TZ episode titled "The Shelter". What makes it all the more hilarious is that, unlike in "The Shelter", Flanders did build his bomb shelter with the intention of letting other people in, but Homer wants to kick him out anyway.
- Hypocrite: Homer condemns everyone (including the Flanders family) for Ned having to leave the shelter when it was Homer's own idea to kick him out in the first place.
- Hypocrite Has a Point: Not that he was wrong in calling everyone out, especially since Ned's own family seemed okay with it.
- Insane Troll Logic: After the comet fails to hit Springfield and burns up in the polluted atmosphere, Moe blames the observatory for the cause of the approaching comet. "Let's go burn down the observatory so this'll never happen again."
- Out of all people in the shelter, the one to leave was Ned Flanders, who built it in the first place.
- The only thing the comet destroyed was the bomb-shelter that was supposed to protect everybody (it also pops the balloon).
- Skinner's been trying to find unnamed objects in the sky for years, to no success. Bart looks through the telescope (unsupervised) for all of three seconds and discovers a comet.
- Jerk with a Heart of Gold: Hypocrisy or not, Homer is the first one to leave the shelter to look for Ned. Moe shortly follows.
- Long List: Kent Brockman, when preparing for the end of Springfield thanks to the eponymous comet, presented a very fast scrolling list of People Who Are Gay. Homer hurriedly tries to copy down the list as it scrolls. The names are actually those of the show's production crew.
- Look Behind You: Database assumes Bart is trying to pull this on the Super Friends, since comets could not be seen in broad daylight and without a telescope, before realising the comet is approaching Springfield.Database: I make it a point never to turn my head unless I expect to see something, Bart.
- Meta Twist: By this point in the series, Homer Simpson has long since proven himself as a man you would not trust at all when it comes to matters of scientific knowledge (or, heck, any knowledge period), but the climax involves his prediction that years of pollution from the nuclear plant has thickened the atmosphere above Springfield to the point that the comet would tear itself apart from the friction until it was "the size of a chihuahua's head" being completely correct (with random chihuahua even appearing to provide a comparison). Bart, Lisa and Homer get scared that the latter turned out to be completely right.
- Mis-blamed: When everything is said and done, Moe pins the blame of the comet almost destroying Springfield... on the town's observatory.
- Model Planning: During the town meeting to discuss how to stop the comet, Professor Frink uses a model of the city of Springfield to illustrate the city's plan to stop the comet by blowing it up with an explosive rocket. Unfortunately, some of the flames from the controlled explosion demonstration wind up falling onto the model's representation of Moe's tavern, setting it ablaze.Moe: Oh, dear God, no!
- Noodle Incident:
- Skinner got even with Principal Kohoutek... "him and that little boy of his."
- Homer's story of how he drove away from some unnamed crime and missed work.
- Frink mentions during the Info Dump regarding the missile that the people who helped him design it worked for the Carter administration and resigned for reasons he doesn't thinks are worth talking about at the moment.
- Off-Model: Near the end of the episode, Apu is yellow instead of brown for a few seconds.
- Persecuted Intellectuals: The people of Springfield rallies into a mob and goes after the observatory and its personnel because they (or at least Moe, who triggered it) believe destroying it will prevent something like this from ever happening again.
- Precision Crash: Played for Laughs: Springfield is hit by a comet; fortunately most of it burns up in the atmosphere so only a small rock lands. It scores a direct hit on Ned Flanders' bomb shelter, which everyone had left mere minutes before.
- Rule of Three: Skinner's Big "NO!" when he finds out Bart discovered a comet, that he just let go of the balloon and read the front page article about how the Prez says school is for losers.
- Screw This, I'm Outta Here!: After Skinner's attempts to down the balloon fail, Bart attempts to flee the scene, to no avail. ("Race you to Utah, Milhouse.")
- After the missile blows the only bridge out of town to bits, and with the airport on the other side, numerous Springfielders try jumping the gap in the bridge with their cars. Emphasis on try.
- Shown Their Work: The numbers that Principal Skinner reads off while observing through the telescope ("6 hours 19 minutes Right ascension, 14 degrees 22 minutes Declination") are actual astronomical coordinates. Principal Skinner is observing in the constellation Orion, just to the east of the star Xi Orionis (about 2/3 of the way between the stars Betelgeuse and Alhena), slowly moving northwards until he reaches 6 hours 19 minutes Right Ascension, 14 degrees 59 minutes Declination, a distance of 37 arcminutes, about the apparent width of the full moon. Bart finds his comet at 4 hours 12 minutes Right Ascension, 8 degrees 7 minutes Declination, in the constellation Taurus, just southwest of the star Mu Tauri.
- Signs of Disrepair: The only bridge out of Springfield is labeled exactly like that when the camera focuses on it. After the missile blows the bridge to pieces, chunks of the sign are also blown away, leaving behind "BRIDGE OUT".
- Smart Ball: Homer predicts that a meteor heading for Springfield will probably burn up in the atmosphere until it's the size of a chihuahua's head. At the end of the episode, it gets lampshaded. "Dad was right!" "I know, kids. I'm scared, too." For added hilarity, the meteor even lands right next to a chihuahua for comparison.
- Storyboarding the Apocalypse: The town hall meeting to discuss the comet and the plan to blow it up with a missile includes showing some slides with crude drawings of what the comet will do to the town. For some reason, the artist felt it necessary to highlight Moe's Bar amongst all of the buildings destroyed by the impact... and make a drawing of the gigantic crater with clearly-labeled charred corpses surrounding it.Moe: Oh, dear God, no!
- Suicidal Overconfidence: The morning after the bridge gets blown away by the missile, multiple Springfield citizens try to jump the massive gorge it was set over to get to the other side and leave town while the news cameras watch on. None of the ones we see try make it, and yet there is still a large conga line of cars right behind them ready to attempt the jump regardless. Artie Pye narrates that this is a typical example of Springfield's "never give up and never think things through" spirit.
- Take That!: The United States Government doesn't come off well in this episode, starting with two jets that are running on Epic Fail Alleged Car levels of inefficiency thanks to government fund cut-offs and later with Congress deciding to leave the entire town to die because some idiot decided it was a perfect thing to attach a pornography rider to the evacuation assistance proposal and thus is promptly struck down. The people who created the Epic Fail of a missile that causes all of the third-act drama are also mentioned by Frink to have worked for the Carter administration and left for undisclosed reasons.Kent Brockman, after seeing the live feed from Congress: I've said it before, and I'll say it again: democracy simply doesn't work.
- Took a Level in Jerkass: Homer's grudge against Flanders escalates from petty jealousy to trying to leave him for dead to the comet. He at least has the graciousness to regret it afterwards (if in a hypocritical tone in which he blames it on the townspeople).
- Unreadably Fast Text: Kent Brockman's newscast:Kent: Now, over the years, a newsman learns a number of things that for one reason or another, he just cannot report. Doesn't seem to matter now, so... the following people are gay. (Long List scrolls really fast up the screen)
Marge: (disgusted) Turn it off.
Homer: (taking notes) Just a second...
- Wham Line: "You don't need a stupid telescope. Its right there!"
- Where the Hell Is Springfield?: The congressman presenting the bill on the evacuation of Springfield from the comet is about to mention the state where the town is when he's interrupted by another congressman attaching a pornography rider to it.
