Springfield Elementary ships out all the poor-testing students ([[MyFriendsAndZoidberg and Principal Skinner]]) on the day of a major standardized test. Meanwhile, Homer has to be extra careful now that his insurance has lapsed and has to wait until 3:00pm to get it reinstated.

!! Tropes:

* ButThouMust: Lisa discovers that the answers for each question have the same meaning. As such, she is unable to decide which one to pick.
* DancePartyEnding
* DaydreamSurprise: We see a DisasterDominoes reaction that kills most of Marge's friends, causing her to freak out because they're uninsured...right before she makes out with the remaining woman, which Homer drools at while watching before it's revealed it was only in his head.
* ExactWords: Principal Skinner tells some students that he's the Principal and they must refer to him as such. Bart then calls him "such".
* FullyAutomaticClipShow: When Homer talks about how insurance pays him everytime he gets hurt, it leads to clips of Homer's AmusingInjuries through the show's run...[[MindScrew including a clip of the Homer clones falling into the gorge from "Treehouse of Horror XIII".]]
-->'''Homer:''' Heh-heh. What a week.
* GettingCrapPastTheRadar: Students make a joke when Principal Skinner instructs them to use a ''number two'' pencil.
* GirlOnGirlIsHot: When Homer has an ImagineSpot about disasters that could happen while not insured, it quickly turns to Marge making out with one of her friends, making him drool.
* OutOfCharacterMoment: Lisa completely chokes on a standardized test with no explanation why while everyone else seems to be able to do it fine including Milhouse. Since the test is thrown out anyway at the end, there's no real telling if the problem was with Lisa or the test itself with Lisa being the only one visibly distraught.
* PottyDance: Ralph does it while on the bus. Skinner asks Otto to stop the bus so Ralph can go to a rest stop, but Otto is mesmerized by the "little girl's dance".
* ReadingForeignSignsOutLoud: In the Russian airing, the actor voicing Skinner somewhat firmly translates the title of Sylvia Plath's ''TheBellJar'' when Lisa is reading it during the final scene.
* ScantronPicture: Bart fills out the answer sheet of his practice test to read "SLURP MY SNOT".
* ShoutOut: The final scene of this is a direct parody of the final scene of the final scene of ''{{Footloose}}''.
