!!This episode contains examples of:
* ArtShift: Homer imagines the kids as freaks with pink skin, no overbites and five fingers.
* 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. 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 used 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 didn'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 Creator/JimmyDurante.
* 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.
* 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".
* RichSuitorPoorSuitor: Mr. Burns and Grandpa Simpson.
* SeriousBusiness: Again, ''{{Matlock}}'' for Grandpa Simpson, as well as Marge's mom.
* ShoutOut: To ''WesternAnimation/TheFlintstones'': Upon arriving at the Simpson household to court Grandma Bouvier, Mr. Burns said Homer, Marge and Maggie must be, respectively, Fred, Wilma and Pebbles. After Mr. Burns gave Homer candy, Homer shouts "[[BorrowedCatchphrase Yabba-Dabba-Doo!]]".
** Abe does Creator/CharlieChaplin's dancing potatoes bit from ''Film/TheGoldRush''. Later on he borrows Creator/JimmyDurante'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.
** Abe interrupting the wedding and running away with the bride is an homage to the ending of ''Film/TheGraduate''.
* SongParody: "The Sound of Grampa", a parody of "The Sound of Silence".
* SpecialGuest: Creator/PhilHartman as Troy [=McClure=].
