Homer: Heh, heh, heh. Yeah, they swore they'd get us back by spiking our water supply. But they didn't have the guts.
Marge: (drinks the tap water) Ooooh. The walls are melting again.
Aliceville and Bobtown are right next door to each other, and they're both fairly quaint, rural towns full of nice loving people...unless you happen to mention one while in the other, in which case all hell breaks loose. The residents of the two towns hate each other with a passion, either due to some old score that remains unsettled or just because they don't like the looks of each other. If it's the former, you can bet the hero will delve into it.
Note that this is sometimes Truth in Television: small towns are more likely to have residents whose families have lived there for generations and often have rocky histories. If something happened a long time ago to spread bad blood between the two, the current population may well continue the fighting, especially if it's over something still relevant such as boundaries or land development. Team sports, particularly football, are a popular focus point for the rivalry now that cattle raids and arson are emphatically discouraged. Besides, sometimes there's not a whole lot else to do.
These towns may have some Feuding Families, or in extreme cases, one town's name may be The Scottish Trope in the other. This trope is also commonly used to throw out the Conflict Ball for a Feud Episode.
- Slayers Try has Alto and Bantone exchange cannon fire every day at the same time. The cause of the war is that the rulers of these countries had a fight when they were kids.
- In a Lucky Luke album, Luke is leading a group of railway builders when they come to the two rival towns East City and West City. Both want the railway to come to their city and when one of them holds a party for Luke and his horse Jolly Jumper, the other attacks. Luke and Jolly flee from the brawl, thinking that they are all crazy. While the inhabitants are busy fighting, the railway gets built right between the two cities.
- The two yards of Lawn Gnomes from Gnomeo and Juliet are towns to the Gnomes, and each side hates the other.
- The two towns on either side of the wall in Dr. Seuss's The Butter Battle Book, named so because the conflict began on how the two groups of people have differing ideas on how butter should be eaten with toast.
- Gulliver's Travels: Lilliput and Blefuscu are neighboring islands which are at war with each other over which end of an egg one should open.
- In P. G. Wodehouse's Jeeves and Wooster story "The Ordeal of Young Tuppy" the towns Upper Bleaching and Hockley-cum-Meston have a heated rivalry which is expressed in the form of an annual rugby game known for its violence and injuries.
- Lancre Town and Ohulan Cutash (which Lancrastians consider a big city because it contains over a thousand people) in the Discworld novels. Their rivalry comes to a head in the annual Morris Dancing championships, which in the Ramtops is an extreme sport.
- A disturbing (and ultimately lethal) version of this occurs in Clive Barker's story "In the Hills, the Cities".
- In The Flying Nun, Sisters Bertrille and Jacqueline find themselves caught between two villages both fighting for the right to be called Santa Thomasina in "The Patron of Santa Tomasina". The two villages are embroiled in disputes over stolen pigs and the statue of St. Thomasina, believing Bertrille to be the reincarnated St. Thomasina. Bertrille manages to bring the townspeople to their senses by employing a Judgment of Solomon gambit, threatening to cut the statue in half and divide it between the two villages unless they reconcile. The two towns decide to place the statue at the fork in the road, and designate themselves as the villages of East Thomasina and West Thomasina.
- Residents of Dog River, the setting of Corner Gas, have a deeply entrenched dislike for nearby Wullerton, to the point that they reflexively turn their head and spit whenever they hear the town's name mentioned. The Dog River - Wullerton rivalry was inspired by the real rivalry between Brent Butt's hometown of Tisdale, Sask. and nearby Melfort. Exploited by Emma in "TV Free Dog River":
Emma: Those in favor of no TV for a week and sticking it to Wullerton, spit!
Fitzy: *bangs gavel* Done!
Oscar: Hey! You tricked us!
- One episode, "Gopher It", shows that the rivalry might be one-sided, since Davis is transferred to the Wullerton police department and now spits whenever Dog River is mentioned, which just confuses the hell out of his new partner. However, that episode was All Just a Dream, or rather a long Imagine Spot by Hank. The Movie later confirms that the rivalry is one-sided. Wullerton is a Sugar Bowl full of incredibly nice, friendly, and selfless people who seem physically incapable of thinking a negative thought about anyone, and even bail out Dog River when the town goes bankrupt. It's implied that everyone hates them because their Incorruptible Pure Pureness just comes across as creepy to regular people.
- Pawnee vs. Eagleton on Parks and Recreation.
- Spanish TV series Villarriba y Villabajo is about two rival adjoining towns - they even share the main square and the bar, even if each town belongs to a different political-administrative division.
- These fictional locales had previously appeared in Spanish TV advertisements where the towns have had their respective fiesta with a huge paella, but Villabajo fails to clean the big paella dish because only Villarriba thought about buying the correct washing liquid.
- Hooterville and Pixley on Petticoat Junction and Green Acres
- The show Jericho had an extreme example. The series follows a small town (specialized in farming and salt mining) in Kansas after the US is hit with about 20 mini nukes. During the series, New Bern (an industrial town) decides to solve its food shortage by taking over Jericho and evicting all its residents.
- The towns of Hatfield and McCoy in No Evil, named after feuding families of the Wild West. It hasn't quite reached actual murder, but that's mostly because spiritual stuff keeps getting in the way (usually involving the main characters). It's mainly a problem because Amaroq adopted McCoy as his "side", and this led them to assume Huey was similarly aligned with Hatfield, meaning the main cast have to get creative when it comes to, for example, healing the sick in McCoy of the Black Tezcatlipoca.
- This is the basic premise of Harvest Moon: The Tale of Two Towns.
- In Mystery Trackers 8: Nightsville Horror the towns of Willowsville and Nightsville have a fairly long-standing rivalry. This presents some problems for secondary characters Sam (a Nightsville resident) and Mary (a Willowsville resident), who intend to run off together.
- In King of the Hill there's Arlen and McMaynerberry.
- In the Avatar: The Last Airbender episode "The Great Divide," the Gaang mediate for two tribes (here used as the nomadic equivalent of towns, not extended families) whose conflict began over either a ritual courier being attacked or a wrongfully accused Good Samaritan, depending on who you ask.
- Stoolbend and Goochland from The Cleveland Show.
- Dimmsdale and Brightburg in The Fairly Oddparents.
- Springfield and Shelbyville from The Simpsons hate each other despite being directly adjacent. It turns out that cause of the hatred is due to Jebediah Springfield falling out with Shelbyville Manhattan, when the latter expressed a desire to marry his cousins in the town they would found together.
Jebediah Springfield: Why would we wanna marry our cousins?
Shelbyville Manhattan: Cause they're so attractive. I thought that was the whole point of this journey!
Jebediah Springfield: Absolutely not!
- South Park, North Park, and Middle Park have this relationship.
- In the VeggieTales segment "The Story of Flibber-O-Loo" (a re-telling of the Good Samaritan story), the towns of Flibber-O-Loo and Jibberty-Lot have a heated rivalry, where they launch shoes and pots at each other with catapults and other devices.
- There are two towns in Montana that were once one combined town called Vida. The split was due to an argument over what to name the place, and so both names are now used for the separate towns on opposite sides of the highway. There's still some contention.
- This is the entire reason Milwaukee came into existence. Before the city was incorporated, there were three small settlements along Lake Michigan and the Milwaukee River: Juneautown, Kilbourntown, and Walker's Point. Juneautown (East Side) and Kilbourntown (West Side) in particular had a rivalry that frequently erupted in violence, culminating in the Bridge Wars on 1845 in which all three bridges that had been erected across the river being burned as each town attempted to isolate the other from it and Walker's Point. As a truce, all three were incorporated as the City of Milwaukee in 1846.
- Minneapolis and St. Paul in Minnesota.
- Cleveland, Ohio and Pittsburgh, Pennsylvania
- Houston and Dallas in Texas.
- Kibbutzim have a tendency to have long-standing rivalries (albeit often in tongue-in-cheek) with neighbouring kibbutzim, e.g. Ha'Ogen and Ma'abarot. There also used to be a rivalry that split up a few kibbutzim based on ideological lines and political party affiliation; ironically, the resulting kibbutzim called themselves "X ikhúd" ('union') and "X meukhád" ('united'), historically supporting (as neither of these parties exists today) Mapai and Mapam respectively.
