* UsefulNotes/AbrahamLincoln: Lisa tries to talk to the Lincoln Monument for advice, but because too many people are there, she goes to UsefulNotes/ThomasJefferson 's Monument instead.
** When Lisa wants to write an essay, she says: "America, inspire me!", whereupon a bald eagle lands on a tree branch and spreads his wings. This pose is a reference to the Great Seal of the United States, complete with arrows in its left claw.
** After witnessing corruption, Lisa watches a group of politicians near the Capitol and imagines them as cats scratching each other's backs and filthy pigs who are fed money by Uncle Sam and wipe their mouths with the American flag.
* BaitAndSwitch: George (H.W) Bush does this with a diplomat when he receives the bill to expel Bob Arnold.
-->'''George Bush''': Okay, this should make my bosses very happy.
-->'''Diplomat''': [[ManBehindTheMan Your bosses?]]
-->'''George Bush''': Yep. All 250 million of them.
* ComicallyMissingThePoint: The Simpsons arrive at the airport where they see a chauffeur holding a sign that reads: "Simpson". Homer then says: "Look, Marge, that guy has the same last name we do!" and hails a taxi instead.

* EagleLand: Zigzagged. The members of government can be corrupt, but Lisa's essay, even though it causes her to lose a contest, is what ends exposing Arnold, showing that people can bring down corrupt forces.
* GettingCrapPastTheRadar: Marge snickers at the phallic shape of the Washington Monument. Homer tells Marge to "grow up".
* LeaningOnTheFourthWall: Homer says: "Oh, Marge, cartoons don't have any deep meaning. They're just stupid drawings that give you a cheap laugh." Then he rises from his chair and reveals his rear cleavage.

* NotSoAboveItAll: The GettingCrapPastTheRadar moment mentionned above.

** The title is this to ''Film/MrSmithGoesToWashington''. The plot is similar too, with Lisa being a patriotic idealist as she enters Washington, becoming disillusioned when she witnesses the corruption there. Just like Mr. Smith, she goes to the Lincoln Memorial to ask him for advice and then uses her talents to criticize the system, which does result in the arrest of the corrupt people she witnessed.
** The Simpsons stay in the Watergate Hotel and visit the IRS Building, the National Air and Space Museum, the Washington Monument, the Jefferson Memorial, the Capitol and the Winifred Beecher Howe Memorial.
** Ted Kennedy can be seen at the contest.
** The satirical pianist is a spoof of Creator/TomLehrer.
* UsefulNotes/ThomasJefferson: Lisa visits his monument.
* TooDumbToLive: After one of the judges suspects Homer of helping Lisa with her essay, she asks him if he's interested in politics or anything for that matter. After Homer shrugs it off with the words "I don't know", the judge asks him to touch his nose with his eyes closed, which Homer fails to do. ''Twice!'' (Before speaking to Homer, the judge suspected he had been giving Lisa help. ''After'' speaking to Homer, she considered giving Lisa extra points for doing so well despite him.)
* VacationEpisode: The Simpsons travel to Washington D.C.
