The Simpsons are forced to go to a ski resort to make use of the skis they bought, but never used. While Homer gets hit in the groin by moguls after [[StupidSexyFlanders being distracted by the mental image of Flanders' butt in a skintight ski suit]] and Lisa nearly gets attacked by deer, Marge ends up the one being injured when a cuckoo clock falls on her leg. While Marge is laid up in the hospital, Lisa steps in as her replacement -- and realizes that it's a lot of work in cleaning up after the slovenly Homer and Bart.

!! Tropes:

* BorrowedCatchphrase: Lisa quotes "Excellent" like Homer's boss, Mr. Burns, when Homer and Bart are convinced they have leprosy, even tenting her fingers while saying it like Burns does.
* DomesticAbuse: Homer and Bart are watching ''Series/ILoveLucy''. All of a sudden, we hear Lucy crying.
-->'''Fred:''' You hit her pretty hard there, Rick.
* {{Irony}}: Marge was the only one who refused to go outdoors while at the ski resort and she was the only Simpson to break a leg.
* MyGodWhatHaveIDone: Lisa when she discovers Homer and Bart have gotten sent to a leprosy treatment facility by the Flanderses.
* StupidSexyFlanders: TropeNamer.
* ThirdPersonPerson: Disco Stu's habit backfires while hitting on Marge.
-->'''Disco Stu:''' Disco Stu wants you to be comfortable while he does his thang.
-->'''Marge:''' Who's Disco Stu?
* TookALevelInJerkass and ArtisticLicenseBiology: Lisa using green paint and oatmeal to simulate leprosy scars (even though the skin-rotting lesions on a leper would actually be red and brown). Granted, Homer and Bart were being obnoxious, but that's a bit harsh.
* TrashOfTheTitans: The Simpson house is, once again, trashed while Marge is away (see also: "Homer Alone"[[note]]season three episode where Marge is arrested for obstructing traffic after having a nervous breakdown over being depended on too much, then, when Mayor Quimby pardons her, Marge decides to leave the family for a weekend at Rancho Relaxo[[/note]], "Marge in Chains," "$pringfield (or How I Learned to Stop Worrying and Love Legalized Gambling)," and "Bart After Dark").
* WorthIt: At some point after their arrival, Homer and Bart realized they didn't have leprosy because one of Homer's lesions fell off, and they found out what it really was. However, they opted to stay at the clinic and endure the painful needles because it meant a Hawaiian vacation.
-->'''Homer''': All we have to do is endure two hours of blinding pain, then it's nothing but sun, surfing and shopping!
-->'''Bart''': Tonight, we're gonna put our fake sores back on, then jump the fence at Club Med and scare the normals!
