While desperately searching for a bathroom during her morning jog, Marge discovers how low-rent Springfield Elementary School really is and moves Bart and Lisa to Waverly Hills Elementary by having Homer rent an apartment there so the city inspector of Waverly Hills (who cracks down on out-of-towners who only register for a Waverly Hills address so they can send their kids to that town's school) does not get suspicious. Meanwhile, Bart helps Lisa become popular by telling others that Lisa is friends with a teenage pop star named Alaska Nebraska.
