Grampa Simpson falls for Grandma Bouvier...and then loses her to Mr. Burns. Meanwhile, Bart steals Homer's credit card to purchase an animation cel--and finds that the animation cel is a rip-off.
!!This episode contains examples of:
* AllOfTheOtherReindeer: Mr. Burns announces all employees who have found true love may leave work early. Homer and various others run for the exits, but one guy stands there sadly and lowers his head.
* ArtShift: Homer imagines the kids as freaks with pink skin, no overbites and five fingers ([[DontExplainTheJoke a.k.a. more akin to real human beings]]).
* BrotherSisterIncest: Homer opposes the relationship between his father and Marge's mother, as a marriage between them would make he and Marge brother and sister (technically stepsiblings). And then their now inbred kids would become "horrible freaks with pink skin, no overbite, and ''five fingers on each hand!''"
* CharlieChaplinShoutOut: Grandpa's bread roll dance is a shout-out to Creator/CharlieChaplin in ''Film/TheGoldRush''.
* ComicallyMissingThePoint: Bart uses Homer's credit card to buy something for $350. After getting the money from Mr. Burns, Bart confesses to him and hands him the money. Homer doesn't seem to understand it was to make up for a loss considering what he planned to spend the money on.
* DisneyOwnsThisTrope: Grandpa is stopped by lawyers for doing unauthorized homages to Creator/CharlieChaplin (even though ''The Gold Rush'' is public domain) and Jimmy Durante.
* TheGraduateHomageShot: When Abraham interrupts Mr. Burns and Mrs. Bouvier's wedding.
* IdenticalGrandson: A photo of Jacqueline Bouvier being arrested for indecent exposure in her youth shows she was ''exactly'' identical to Marge.
* JumpingOutOfACake: The guys at the retirement home try to cheer up Grandpa with a stripper on a cake, but she apparently died while being wheeled out.
* LogoJoke: Grampa rambles over the entire end credits, until finally piping down when the Gracie Films logo shushes him.
* MexicanStandoff: Between Bart and Mr. Burns, with a pair of condiment guns.
* OldTimeyAnkleTaboo: Jacqueline Bouvier recounts how she was arrested for wearing a OldTimeyBathingSuit because it exposed her ankles.
* OnlyFriend: During the wedding, the only guest on the groom's side is a German soldier from World War I.
* PetTheDog: Mr. Burns is so thrilled with his new relationship that he lets all employees who have found true love leave work early.
* ProductPlacement: Parodied when Grandpa Simpson and Grandma Bouvier demand that Bart and Lisa sing the "Armour Hot Dogs" jingle. When the Simpson/Bouvier families join in, Homer walks through the scene holding a sign saying "Please buy Armour Brand Hot Dogs".
* RattlingOffLegal: When Roger Meyers Jr. guarantees that each ''Itchy & Scratchy'' cel will increase in value, an announcer quickly states, "Not a guarantee."
* RichSuitorPoorSuitor: Mr. Burns and Grandpa Simpson.
* SeriousBusiness: Again, ''Series/{{Matlock}}'' for Grandpa Simpson, as well as Marge's mom (and most of the elderly people in Springfield).
* ShoutOut:
** To ''WesternAnimation/TheFlintstones'': Upon arriving at the Simpson household to court Grandma Bouvier, Mr. Burns is convinced by Smithers that Homer, Marge and Maggie must be, respectively, Fred, Wilma and Pebbles. After Mr. Burns gives Homer candy, Homer shouts "[[BorrowedCatchphrase Yabba-Dabba-Doo!]]".
** Abe does Creator/CharlieChaplin's dancing potatoes bit from ''Film/TheGoldRush''. Later on, he borrows Jimmy Durante's catchphrase, "Good night, Mrs. Calabash, wherever you are", replacing "Bouvier" for "Calabash". In both instances, he is approached by lawyers who demand he put a stop to his unauthorized imitations.
** Bart and Burns point guns at each other like Mr. White and Mr. Pink in ''Film/ReservoirDogs''.
** Abe interrupting the wedding and running away with the bride is an homage to the ending of ''Film/TheGraduate''.
* SkewedPriorities: When Nelson has an out-of-body experience at the Kwik-E-Mart (done to tell Bart, "Haw haw!" from afar), all Apu can think about is how it's bad for business.
* SongParody: "The Sound of Grampa", a parody of "The Sound of Silence".
* SpecialGuest: Creator/PhilHartman as Troy [=McClure=].
* StrangeMindsThinkAlike: Bart and Homer "accidentally" bumping into each other: Bart to get his father's wallet, Homer to get his son's ''slingshot''.
* TakeAThirdOption:
--> '''Grampa''': Mrs. Bouvier! Honey, are you sure you want to be Mrs. Montgomery Burns? Wouldn't you rather be Mrs. Abraham J. Simpson?\\
'''Mrs. Bouvier''': No.\\
''(Abe frowns in disappointment; Mr. Burns approaches)''\\
'''Mrs. Bouvier''': I don't want to be ''either''.\\
'''Grampa''': Hot-ziggity-zam! That's good enough for me!
* WouldHurtAChild: PlayedForLaughs via RuleOfThree: an attorney for Frank Sinatra, a golf course attendant and a delivery man all punch Bart in the nose (believing him to be Homer) for various indiscretions he committed. Even the episode's [=DVD=] commentary lampshades how the three men had no qualms about punching a child in the face.
* YouWannaGetSued: Grampa gets stopped by a lawyer at different points in the episode whenever he tries to emulate other celebrities.
