In this parody of ''Disney/OneHundredAndOneDalmatians'' (both the cartoon and live-action films), Santa's Little Helper cuts a destructive path across the Simpson house, which leads him to the dog track from "Simpsons Roasting On an Open Fire", where he mates with a female dog racer named "She's The Fastest" and becomes the father of 25 greyhound pups that Mr. Burns wants for his wardrobe.

!!This episode contains examples of:

* ActuallyPrettyFunny: After Mr. Burns sings about how he's going to make the puppies into a suit, Bart finds himself humming the song.
-->'''Lisa:''' ''Bart!''\\
'''Bart:''' Sorry. You gotta admit, it's catchy.
* AdaptationalVillainy: In her short cameo during "See My Vest", Nanny goes from a caring, gentle figure toward dog puppies to openly supporting Mr. Burns' plan to slaughter them and turn them into a coat. PlayedForLaughs of course.
* TheCameo: Nanny from ''Disney/OneHundredAndOneDalmatians'' appears briefly during "See My Vest".
* CelebrityResemblance: Mr. Burns thinks one of the dogs standing on its hind legs looks like Rory Calhoun, of all people. What makes this particularly funny is that Smithers immediately knows who Burns is referring to, despite just a vague description given.
* ChekhovsGun: The puppies' habit of chewing on Bart's socks.
* ClaspYourHandsIfYouDeceive: Mr. Burns does this when scheming how to steal the puppies.
* ComicallyMissingThePoint: Chief Wiggum doesn't suspect that the 25 puppies Mr. Burns recently "found" might be the same ones the Simpsons lost.
** Earlier, he thought they were looking for their wallet.
* CostumeTestMontage: Mr. Burns while singing his VillainSong.
* {{Crossdresser}}: Bart complains that because the puppies ate his socks, he has to wear Lisa's socks to school.
--> '''Homer''': How do you explain the culottes, boy?\\
'''Bart''': ''(wearing a skirt)'' Well, I have to coordinate, don't I?
* CruellaToAnimals: Mr. Burns plans to make the dogs into a suit. He has a whole wardrobe full of clothes made from animals, and one line in his song implies that he's willing to use his human servants if necessary.
* CutenessProximity: Mr. Burns tries to kill the dogs, but finds that he can't bear to do so because of their PuppyDogEyes. He then turns his gun towards Bart and Lisa, but they make sad faces and whine as well, and Burns relents.
* DescriptionCut: When Homer and Marge think about selling the puppies because they're too expensive and a hassle:
--> '''Lisa''': Is that what we do in this family? When someone becomes an inconvenience, we just get rid of them?!\\
''(cut to Grampa at the retirement home)''\\
'''Grampa''': ''(picks up phone)'' Hello? Is anybody there?
* DidNotThinkThisThrough: Bart hopes a litter of newborn pups will attack a bully for him.
** The Simpsons are eager to give the puppies away and Homer is left kicking himself when they realize how much those dogs were worth.
* DoubleStandard: The Simpsons think it's cute when one of the puppies puts its paws on the TV screen. Snowball II tries it too, and isn't so lucky.
--> '''Homer''': GET THAT CAT OUT OF THE WAY!! ''(Snowball II moves and the Simpsons eye her angrily)''
* DrivenToSuicide: It at first appears that Homer hung himself after losing millions of dollars from giving the racing dogs to Burns. Subverted in that he's actually swatting a lightbulb in the basement.
* EscapedAnimalRampage: Kent Brockman is reading the news in front of a window:
--> ''In today’s news, a two-ton rhino escaped from the Springfield Zoo. But zoo officials were quick to act, and Petunia, as she is known, is safely back in captivity. [A rhino appears outside the window and attacks the audience] In other news, a three-ton rhino that escaped from the zoo last week is still at large.''
* FunnyBackgroundEvent: The EscapedAnimalRampage above, playing out behind an oblivious Kent.
* GettingCrapPastTheRadar: Getting past nothing. We actually see Santa's Little Helper ''mounting'' She's The Fastest, albeit from the shoulders up (some versions do exist where the shot is not cropped and viewers do see more of SLH mounting She's The Fastest).
-->'''Bart:''' It looks like he's trying to jump over her, but he can't quite make it.
** Bart calling She's The Fastest a "bitch", which Marge feels is wrong. However, like Bart using "bastard" to describe Homer's half-brother[[note]]since he was born out of wedlock, which is what "bastard" originally means[[/note]], Bart is using "bitch" right in this context, since She's the Fastest is a female dog and that's the real definition of that word. However, because "bitch" is used more as a derogatory term for a woman or a man who doesn't act manly (or to describe something that's unfair or awful, as seen in the phrase "Life's a bitch and then you die"), people rarely use the word "bitch" to mean "female dog."
* HandWave: Bart and Lisa escape Mr. Burns by sliding down the laundry chute. When they hit the floor, they start to run but are cut off by Mr. Burns:
--> '''Bart''': That's ''impossible''! How did you get here first?!\\
'''Mr. Burns''': Oh, there'll be plenty of time for explanations later. Right now, I think I'll be taking my puppies back.
* IAmSpartacus: Invoked by Bart as he makes all the puppies stand up to get closer to his socks.
* MeaningfulName: Parodied during the dog race, where Homer tells Marge he bet on She's The Fastest based solely on her name. Marge tells him that STF's name shouldn't be taken literally, but not only does STF take the lead in the race, but the announcer reveals the names of two other race dogs: "Always Comes In Second" and "I'm Number Three".
* NeedleInAStackOfNeedles [=/=] ShellGame: Burns has decided to spare one of the puppies after it stands up on its hind legs. Bart hides him among the other puppies to keep Burns from shooting them all. Burns tries to single him out by having him do his trick, but Bart then dangles some socks behind Burns to get all the dogs to stand up.
* NoJustNoReaction: When Santa's Little Helper has sex with She's The Fastest, the race track announcer can only bring himself to say: "Ladies and gentlemen, this is the end. This is the end of dog racing."
* NotWhatItLooksLike: Homer's shadow in the basement. To Marge it first looks like Homer hanged himself.
* OffscreenTeleportation: Lampshaded by Bart wondering how fast Mr. Burns and Smithers could reach the basement.
* OverlyLongGag: The puppies eating Homer's chips.
* PetTheDog: Mr. Burns decides to spare one of the dogs because it can stand on its hind legs. He eventually spares them all.
* SarcasmFailure:
--> '''Lisa''': They're [the greyhounds] our's! You stole them from us!\\
'''Mr. Burns''': Here's a phone. Call somebody who ''cares''.\\
''(Lisa immediately dials 911)''\\
'''Mr. Burns''': ''(grabs phone)'' Give me that!
* SeeYouInHell: Subverted:
--> '''Lovejoy''': See you in Hell! ''(slams door, but pokes it back open)'' ...from Heaven. ''(slams door)''
* ShadowDiscretionShot: When Homer appears to hang himself. (He's actually holding on to the rafter and swatting the lightbulb, which makes the shadow appear to be swinging.)
* ShootTheDog: Mr. Burns is attempting exactly that but cannot bring himself to do it.
* ShoutOut:
** The entire plot is a WholePlotReference to ''Disney/OneHundredAndOneDalmatians''.
** The song "See My Vest" spoofs "Be Our Guest" from ''Disney/BeautyAndTheBeast''.
** Santa's Little Helper and She's The Fastest's date parodies ''Disney/LadyAndTheTramp''.
** One of the puppies is named [[Music/{{Prince}} The Puppy Formerly Known as Prince]].
** Santa's Little Helper briefly [[Film/Terminator2JudgmentDay changes his shape]] to squeeze out the car window.
* SkewedPriorities: When the Simpsons are supposed to be looking for the escaped Santa's Little Helper, Homer is seen at the betting window.
--> '''Homer''': Two bucks to win on number eight. ''(notices Marge; changes tone)'' And have you seen my beloved dog? ''(fakes crying)'' Gimme the ticket.
* SpaghettiKiss: Parodied when Santa's Little Helper and She's the Fastest end up fighting over the strand.
* SpinningClockHands: As the family watch the puppies being born, after they count 24 the clock on the wall is shown spinning to a few hours later, after which the count is... 25.
* TemptingFate: Deconstructed. All three guests to Marge's dinner are so full of praise, that it could only end in misery.
** A second example occurs later when Lisa accuses Burns of stealing the puppies. Monty hands her a phone and sarcastically tells her to "call someone who cares". Lisa promptly dials 911. (Burns yanks the phone out of her hands before the call connects).
* TooDumbToLive: After Homer noted that Mr. Burns is dangerous to the puppies, he, Marge, and Lisa simply walk away from the unsupervised box containing all puppies while Mr. Burns came back and stole each one of them behind their backs. [[LampshadeHanging Smithers criticizes Mr. Burns for using such a simple scheme]].
* TouchTelepathy: Parodied. The pet shop employee mind-melds with the Simpons' dog in order to increase sales.
* UnplannedCrossdressing: Bart has to wear some of Lisa's socks because his own fell victim to the dog puppies. He's also wearing a skirt [[RuleOfFunny because he has to coordinate]].
* VillainSong: "See My Vest".
* ViewersAreGeniuses: Anyone without a film degree, any idea who Rory Calhoun was?
* WholePlotReference: To ''Disney/OneHundredAndOneDalmatians''.
