Homer buys a handgun to better protect his family after a soccer riot plagues the town much to Marge's dismay.

!! Tropes (YMMV tropes can be found [[YMMV/TheSimpsonsS9E5TheCartridgeFamily here]]):
* BothSidesHaveAPoint: The writers tried to give both sides of the gun rights debate reasonable arguments. WordOfGod says that if there is any message in the episode, it is that irresponsible idiots like Homer shouldn't own guns.
* {{Bowdlerization}} and [[BannedInChina Banned in the UK]]: The heavy references to guns and scenes glamorizing and playing gun misuse for laughs got this episode banned on most UK channels. The few times the episode did air on UK TV had to have scenes of gun misuse and scenes of guns shown in a glamorizing light edited (specifically, the ending where Marge goes to throw the gun away in the motel trash, but catches herself in the reflection and keeps it, as it makes her look sexy). The episode does appear on the PAL VHS release "The Simpsons: Too Hot for TV" and the complete season 9 DVD set.
* CallBack: Among the many incidents from Homer's background check are fighting GeorgeHWBush in "Two Bad Neighbors" and being institutionalized in "Stark Raving Dad".
* EveryoneHasStandards: Springfield's NRA members (which include a bitter, emotionally abusive old woman[[note]]Principal Skinner's mom[[/note]], a Mafia henchman[[note]]Louie[[/note]], a surly bartender[[note]]Moe[[/note]], a DepravedKidsShowHost[[note]]Krusty the Clown[[/note]], a single mother who stole her lazy husband's convertible to get him to pay child support[[note]]Ruth Powers[[/note]], and a gun-crazy redneck[[note]]Cletus the Slack-Jawed Yokel[[/note]]) are shocked at how recklessly Homer uses his gun.
* LostAesop: Marge and Homer are at odds over the gun he buys, which even leads Marge to briefly leave him. In the end, Homer finally agrees to let Marge get rid of the gun, so Marge heads to the nearest garbage bin to throw it out. However, seeing herself holding the gun from a reflection in the lid, she likes how dangerous and cool she looks so she decides to hold on to the gun, putting it in her purse. The writers said that there was no real message from the story, but if there was, it'd be that people like Homer Simpson should not have a gun, so... mission accomplished?
* PowderKegCrowd: Springfield descends into a full-blown riot out of ''sheer boredom''.
* StrangeMindsThinkAlike: When Lisa told Homer the Second Amendment was just a relic, Homer conter-argued that it keeps them safe from the King of England. Later in the episode, when the [=NRA=] learned how irresponsible Homer was with his gun, Krusty started berating him by claiming that guns should be used for "family protection, hunting dangerous or delicious animals, and keeping the King of England out of your face."
* TakeThat: The reason the soccer riot starts is because the soccer game is incredibly slow and boring.
-->'''Krusty:''' Come on, you schnorrers, '''do something!'''
* WhatHappenedToTheMouse: The soccer riot was never resolved in this episode, and was only there as a cheap set up for Homer wanting to buy a handgun.
