After Marge gets mugged by a hobo outside of the Kwik-E-Mart's bathroom, she turns into a recluse afraid to even leave her own basement. Eventually, she becomes bored, and starts turning to weight lifting (from some weights Homer bought at Rainier Wolfcastle's bankruptcy sale) to pass the time. After gaining the courage to go outside and beating up the hobo who mugged her, she becomes a bodybuilder, thanks to her old friend, Ruth Powers, who [[NoodleIncident went to jail, got addicted to bodybuilding and steroids, and became Miss Mexican Mafia]].

!!This episode has examples of:
* AmazonianBeauty: Marge becomes one in the third act. However, with her steroid abuse later on, she becomes a...
** BrawnHilda
* BrokeTheRatingScale: During an attempt by the family to help Marge overcome her agoraphobia, she is told to describe her anxiety level using a number from one to ten. However, while Homer attempts to get rid of a beehive, Marge says "12," then "15". When the swarm of bees attack the family, Marge screams, "703!"
* DoubleStandardRapeFemaleOnMale: After bulking up, Marge has sex with Homer (who is clearly scared and doesn't want to) violently enough that it hurts to walk the next morning. It's played for laughs, with Marge [[KarmaHoudini never apologizing or repenting, and getting away with it]].
* FromBadToWorse: The family attempts to simulate the Kwik-E-Mart experience at home to ease Marge back into going outside, but it ends up making her agoraphobia even worse than before, driving her into the basement.
* [[HeWhoFightsMonsters She Who Fights Monsters]]: Marge's decision to bulk up is prompted by a thug robbing her, which leads to an epic CurbStompBattle when she catches up with the thug. That said, she ends up becoming an aggressive bully.
* {{Hypocrite}}: {{Discussed|Trope}} when Marge initially refuses to take drugs due to her noting that it'd make a hypocrite out of her anti-drug bumper sticker-laden tail gate. She ends up taking the drugs anyway after succumbing to peer pressure from Ruth.
* [[IKnowYoureInThereSomewhereFight "I Know You're In There Somewhere" Talk]]: Homer tries to talk down a raging Marge in Moe's Tavern after she was done [[NoHoldsBarredBeatdown beating up all the men in the bar]]. She has a HeelRealization and steps down.
* NoGuyWantsAnAmazon: Bart's reaction after seeing the "Iron Maidens."
--> '''Bart''': Ay caramba. I'm off women forever.
* PoliceAreUseless: When Marge catches the thug herself, [[HypocriticalHumor Chief Wiggum blames his coworkers about not catching the thief themselves]].
* SecondPlaceIsForLosers: Marge gets second place in the Iron Maiden competition which leads to this conversation.
--> '''Marge''': From now on, I'm going to up my carbo load, use a ''denser'' ripping gel--\\
'''Homer''': '''''Denser'''''?\\
'''Marge''': *slams her fist down* Damn straight! ''[[{{Squick}} I didn't sacrifice my period for second place!]]''
* ShoutOut: When Marge started taking steroids, the theme song for {{Popeye}} started being heard.
** Marge beating up the mugger is nearly a shot-for-shot recreation from the scene in ''Film/TheGodfather'' in which Sonny beats up his sister's abusive husband.
** During the [[TheTetrisEffect Tetris]] sequence, music from the GameBoy version of the game plays, followed by a fanfare from the NintendoEntertainmentSystem version when Homer realises he left no room in the car for himself.
* StockFootage: The entire "Eye on Springfield" intro is reused from the episode "[[Recap/TheSimpsonsS3E10FlamingMoes Flaming Moe's]]". Needless to say, to go from Season 3 animation to Season 14 animation is jarring.
* TheTetrisEffect: Homer uses his experience in playing Tetris to fit everything he bought in Rainier Wolfcastle's bankruptcy sale and his family in the car. [[EpicFail Unfortunately, he forgot to include himself in the equation]].
