First Aired - 9/4/1994
A summer heat wave's hit Springfield and beating that heat is a challenge for everyone. Hans Moleman gets set on fire after his Coke bottle glasses refract the sun the way a magnifying glass does to ants, Principal Skinner is up to his knees in the original cast of ''M*A*S*H'' at the Springfield Wax Museum, and a hippie singing "Sunshine On My Shoulders" on the street gets punched in the face by an angry passerby.
The kids on Evergreen Terrace get brief respite when a travelling pool (driven by Otto) stops by, but soon enough it has to move on. Bart and Lisa, having "developed a taste for" swimming, ask Homer to get them a pool of their own. Not wanting to spend the summer being nagged about the issue, he agrees to it.
Once the family's set up their new above-ground pool in the backyard, the Simpson house is ''the'' place to be for the neighborhood kids. Unfortunately, on the first day Bart falls from his treehouse when a Nelson Muntz prank goes awry, and breaks his leg. He is subsequently confined to his room, and, able to see the pool from it, becomes jealous of the newly-popular Lisa. He's also bored out of his mind, and (bitterly) accepts Lisa's offer of her telescope to occupy his time. Spying on the various neighbors, in true ''RearWindow'' fashion he comes to believe that Ned Flanders has murdered his wife Maude and buried her in the yard.
When Martin Prince gets an even nicer pool in his backyard, the neighborhood kids desert Lisa's house for his. When she visits Bart, he tells her about Ned and forces her to sneak into his house while he's out and figure out what's going on. When he comes home and it looks like she's in danger too, Bart drags himself over there to save her. But in truth, what Ned buried in the yard was a dead houseplant. (Maude was out of town at a Christian retreat, and she had entrusted the plant to his care. As for the scream that sounded like her getting killed? [[Main/ScreamsLikeALittleGirl That was Ned,]] after he saw that the plant had died.) Meanwhile, Martin's own surge in popularity comes to an abrupt end when his pool is overcrowded by kids and bursts apart.
!!!This episode contains examples of:
* BadHumorTruck: Downplayed with the ice cream truck that looked normal, but really had no more ice cream; parodied with a rebuilt ice cream truck that only sells Texas-style chili and boiling hot ginger ale.
* BitingTheHandHumor: After Homer says, "She's such a fox" in reference to Maude, he changes the line to "What's on FOX tonight? Something ribald, no doubt." At the time the episode first aired, the live-action sitcom ''Martin'' had moved to 8:30 pm (eastern standard), and, as elaborated on further in "Bart's Girlfriend," the show was ribald[[note]]meaning, "crude or sexual in a funny way"[[/note]] -- though not as much as any other show on the line-up at the time, and that included ''MarriedWithChildren''.
* BusbyBerkeleyNumber: The Esther Williams variant is parodied as the kids make Lisa the star of the pool.
* CrazyPrepared: Martin wears ''17'' bathing suits at the pool mobile, knowing that bullies will take his. When he brags about it, the bullies take them all instantly. "I brought this on myself."
** Apparently the Springfield police have a code for regicide.
* EarlyInstallmentWeirdness / OldShame: In-universe: The ''Classic Krusty'' reruns (which Krusty doesn't like, judging by his disgusted tone in introducing the episodes) reveal that ''The Krusty the Klown'' show was originally a socio-political talk show
* ForInconveniencePressOne: Bart's attempt to call the police.
* FunnyAneurysmMoment: Bart worrying that Maude is dead doesn't seem so funny now that Maude really did die on the season 11 episode "Alone Again, Natura-Diddly."
* NoodleIncident: Bart getting Grampa tarred and feathered 20 minutes before telling the rest of the family about Flanders' possibly murdering Maude. We don't know what Bart did to Grampa to make that happen.
** We also don't get to see how Lisa gets out of the pool after being stranded when it empties (though it can be assumed that Marge got her out or she struggled to pull herself out).
* SanitySlippage: Bart when he confines himself to his room after breaking his leg.
* SarcasmMode: Subverted. Homer sounds sarcastic near the end of the episode but he was being serious.
* ScreamsLikeALittleGirl: Ned.
* ShoutOut: To ''Film/RearWindow''. [[LampshadedTrope Lampshaded]] when Bart starts spying on the town and finds JimmyStewart, also with his leg in a cast, doing the same thing.
** The Itchy & Scratchy episode has one to the pilot of Series/StarTrekTheOriginalSeries.
* TemptingFate: Bart assumes he can just spend the whole summer watching Krusty. At which point Krusty announces he's going on vacation and showing boring re-runs.
* TookALevelInDumbass: When Lisa becomes popular she decides she doesn't need her brain anymore. It returns when everyone leaves for Martin's pool, mostly to gloat.
