In this episode as well as Bart-Mangled Banner the Simpsons are thrown in jail even Maggie. However in Who Shot Mr. Burns? (Part Two) Chief Wiggum refused to arrest her, unless he was pretending it because Mr. Burns is a villain and Maggie wouldn't have been arrested for shooting him.
When the Simpsons were playing Monopoly, Bart had multiple hotels and houses, however you are only allowed up to 4 houses and once you have 4 houses you are then allowed to purchase 1 hotel which replaces the houses.
When the Simpsons were playing Monopoly, Lisa mentions that Bart bought Marge a house, however you are not allowed to purchase anything for other players or share money, because that would be cheating.
When Marge asks if Bart could drive the car, he says it’s his first time which is an obvious lie which is why he pulls out a key and driving gloves. Bart had a driver's license and drove in "Bart on the Road"; everyone in the family knew this except for Marge. Bart also drove in "Burns' Heir", "Bart Carny" and "The War of the Simpsons" before this episode.
In Viva Ned Flanders, Homer tries to get Ned to accept being a polygamist on the basis that having two wives can be great. Homer imagines himself lazing in a hammock while Marge and Amber do yard work. This episode is far different, where Marge is clearly unaccepting of having Amber in the house. This once again shows how reality is often far different from Homer's fantasies.
As Marge and Homer's marriage from the episode 'A Milhouse Divided' was void, this meant that Homer's marriage to Amber in 'Viva Ned Flanders' was not bigamous.
Lisa nearly breaks the fourth wall in this episode when she says "Could this be the end of our series..." but finshes saying "....of events."
It could also be the inspiration of the comic Brawl in the Family by Matthew Taranto, whose title actually comes from the video game Super Smash Bros. Brawl (the comic is centered around Nintendo characters, mainly Kirby ones).
