The '''''MGM Oneshot Cartoons''''' are a [[ExactlyWhatItSaysOnTheTin series of oneshot cartoons]], produced by Fred Quimby for {{MGM}}'s in-house cartoon studio. Many of these shorts were directed by [[Creator/HarmanAndIsing Hugh Harman and Rudolf Ising]], as well as future star directors [[Creator/HannaBarbera Bill Hanna and Joe Barbera]].

Aside from the first two and last two made, the bulk of these cartoons were made from [[UsefulNotes/TheGoldenAgeOfAnimation 1939 to 1943]]. The shorts were made in an attempt to find a new star series for {{MGM}}, as well as to make up for the previous failures of ''The Captain And The Kids'' and ''Count Screwloose''. One of these experiments, ''WesternAnimation/PussGetsTheBoot'', would wind up launching {{MGM}}'s acclaimed ''WesternAnimation/TomAndJerry'' cartoons. Another notable oneshot was the anti-war short ''WesternAnimation/PeaceOnEarth'', the only cartoon to ever be nominated for a Nobel Peace Prize, and to be voted as one of The50GreatestCartoons in 1994.

These shorts were succeeded by the WesternAnimation/TexAveryMGMCartoons, many of which were also oneshot cartoons, although two final oneshots were produced in the 1960s by Creator/ChuckJones for the studio while he was working on his ''Tom and Jerry'' shorts.

* Literature/TheDotAndTheLine

* ''WesternAnimation/TheBearThatWasnt'': Directed by Creator/ChuckJones, adapted from the story by Creator/FrankTashlin.
* AllJustADream: The end of "The Little Goldfish".
* AnimationBump: When Creator/HarmanAndIsing were brought back in 1939 to give the MGM Cartoon Studio the kick in the pants it needed, they had used the time in their absense to considerably refine their animation skills to the point of full-blown Disney quality, resulting in TheTwelvePrinciplesOfAnimation being in full effect in these shorts. It helped that Harman And Ising had in fact worked on one outsourced ''WesternAnimation/SillySymphonies'' short, "Water Babies", during that time.
* AntiVillain: The eponymous wolf of "The Hungry Wolf"; he ''does'' want to eat the little kid rabbit who unwittingly comes to his house, but it's clear he was literally starving to death in the first place, and eventually the wolf gets guilty enough about his desires to where he forcibly throws the rabbit out to keep himself from eating him--which fails and he tries to go after him, only for the snowstorm to get the better of him. Ironically, the rabbit and his family take him in during the storm, and the wolf is very grateful for this.
* ArtisticLicenseAstronomy: "The Milky Way", which has literal milk. Also "Little Buck Cheeser" with it's cheese-moon.
* AscendedExtra: The donkey from "Little Gravel Voice" would later make a couple appearances in the WesternAnimation/BarneyBear cartoon series, and even became a recurring character in the Barney Bear comics, even receiving the name of Benny Burro.
* BittersweetEnding: "The Little Mole"; the kid gets his new glasses broken and comes close to drowning, but he ends up reunited with his mother by the end, and he can once again see his "Dream Castle" (a pile of junk which he imagines is the former due to his very poor eyesight).
* BigFriendlyDog: The family of Saint Bernard rescue dogs in "Little Cesario"; ironically inverted with Cesario himself in terms of size, but he's still just as friendly.
* TheCameo: [[WesternAnimation/TomAndJerry Spike the Bulldog]] makes a brief cameo in "War Dogs".
* CarnivoreConfusion: "The Hungry Wolf", in which a starved wolf just can't bring himself to eat the cute little bunny who shows up at his doorstep (though he almost does).
* CigarChomper: The Spider in "Mrs. Ladybug".
* CrouchingMoronHiddenBadass: "Little Cesario", a Saint Bernard pup who initially seems rather unhelpful, but became instrumental in saving the older Saint Bernard, Alexander, from a heavy snowstorm and avalanche.
* CryingWolf: "The Boy and the Wolf".
* CuteButCacophonic: The donkey from "Little Gravel Voice"; his bray is not only extremely obnoxious, but literally ''harmful'', as the wolf it encounters later finds out the hard way.
* CuteKitten: The trio of kittens in "The Milky Way".
* DenserAndWackier: "The Lonesome Stranger", a parody of western cartoons, is noticably more gag-oriented and wild in it's animation than most of these other shorts. Apparently, Hugh Harman made it as part of a bet with producer Fred Quimby to prove he could do comedy in the vein of Creator/TexAvery and Creator/BobClampett.
* DigitalDestruction: When the shorts were restored for TV airings, many of them went through the DVNR process, which unintentionally scrubbed away a lot of the detail and linework from many shorts, such as "Gallopin Gals and "Tom Turkey".
* DogFace: Officer Pooch, from the eponymous short.
* DoubleTake: In "The Little Mole", Dr. Primrose Skunk reacts this way when the mole points him to his dream castle (actually a pile of junk that he mistakes as a castle due to his poor eyesight above ground).
* FamilyUnfriendlyDeath: The fate of the Spider in "Mrs. Ladybug"; after unwittingly swallowing his cigar to hide it from the nearby kid, it burns him from the inside and he drinks something nearby to put it out--only to find out it was a jug of gasoline! Seconds later, he violently explodes and is sent to Kingdom Come.
* FluffyCloudHeaven: The spider in "Mrs. Ladybug" ends up here after unwittingly blowing himself up.
* FurryConfusion: "Officer Pooch" has both a DogFace and a non-anthropomorphic dog.
* GetOut: The Wolf from "The Hungry Wolf" angrily says this several times to the kid rabbit before forcing him out of his house, [[JerkassFacade but it's to keep himself from trying to give in to eating the kid.]]
* JerkassFacade: The Wolf from "The Hungry Wolf" angrily throws the kid rabbit out of his house, in an attempt to keep himself from trying to eat him.
* IJustWantToHaveFriends: The premise of "Little Gravel Voice"; the protagonist is a cute, friendly little donkey who suffers from having a bray so dreadfully obnoxious that it scares away all the other animals. Ironically, his bray ends up harming and scaring away a hungry wolf, which earns him the friendship of the other animals--once they tie up his snout with his ears, of course.
* LimitedAnimation: "The Dot and the Line".
* MusicalEpisode: Several of them are, like their predecessor series ''Happy Harmonies''.
* NoCelebritiesWereHarmed: "Art Gallery" features several caricatures of famous movie stars of the day. "Gallopin' Gals" also features caricatures of female celebrities of the time period.
* PublicDomainSoundtrack: "Blue Danube", although there are custom lyrics made for it in the short.
* {{Rotoscoping}}: Used in ''Blue Danube'', ''Goldilocks'' and ''WesternAnimation/PeaceOnEarth''.
* SentientVehicle: At one point in "Innertube Antics", when the eponymous tube rips the donkey's old Jalopy out of its frame, it crashes through his house's wall--and is found relaxing on the bed, smiling.
* ShaggyDogStory: "Art Gallery". Once it looks like Nero has succeeded in burning down the art museum, everything abruptly returns back to normal.
* SpiritualSuccessor: Many of them are essentially ''Happy Harmonies'' with more lavish animation, hence why a few of these shorts featured previous stars of the ''Harmonies'' shorts.
* SmellySkunk: Dr. Primrose Skunk from "The Little Mole"; his first appearance has several flowers go limp as he walks by.
* SnakeOilSalesman: Subverted with Dr. Primrose Skunk from "The Little Mole". He's meant to give off an air of this kind of character, but he isn't evil and even gives the eponymous mole a pair of glasses (only taking some pocket change as a meager fee). The worst thing he does is shatter the kids illusion about his dream castle (a pile of junk that he mistook for a castle due to his poor eyesight above ground) and let him wander off unsupervised.
* {{Transflormation}}: "The Tree Surgeon" revolves around an unintentional one.
* TheTwelvePrinciplesOfAnimation: In full-blown effect. The shorts are very solidly drawn, and the films are loaded with more squash and stretch and secondary actions than you can imagine.
* VillainousBreakdown: The wolf from "The Hungry Wolf" is driven to this when he kicks the kid rabbit out of his house to keep himself from eating him, and then succumbs to his hunger shortly after. Thankfully, the snowstorm outside gets the better of him, and the rabbit and his family save him and welcome him into their house (and the wolf is grateful for this).
* TheVoiceless: Pantomime was frequently used in the shorts, with some characters having no dialogue whatsoever. "Officer Pooch" is a notable example of this.
* WartimeCartoon: "War Dogs" and "The Stork's Holiday". "Innertube Antics" is not an explicitly war-themed cartoon, although the rubber scrap drive of the short is an obvious nod to the strict rationing of rubber during the war years.
* WholesomeCrossdresser: The Crow in "The Bookworm" tries to lure out the worm by attempting a "Little Bo Peep" sham. [[GenreSavvy The worm isn't fooled.]]
