Lisa becomes a finalist in a patriotic essay contest and travels to UsefulNotes/WashingtonDC, only to have her faith in the American way shattered when she witnesses a senator taking a bribe and planning to destroy a forest.

!! Tropes:
* 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.
* {{Allegory}}:
** 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.
* 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.
* DudeWhereIsMyRespect: When Lisa tries to ask Thomas Jefferson's monument for advice Jefferson feels angry because, compared to Lincoln, nobody visits him. Then, in a SarcasmMode, he starts naming all the so-called "unimportant things" he did for the United States.
* GettingCrapPastTheRadar: Marge snickers at the phallic shape of the Washington Monument. Homer tells Marge to "grow up."
* GenreSavvy: 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.
* NakedOnArrival: The Simpsons visit the White House, where they see Barbara Bush taking a bath. At first, she is startled, but then she just starts guiding them about the room.
* ShatteringTheIllusion: Lisa arrives in Washington to show off her patriotic pride with an essay, but loses faith in the American way when she witnesses a senator taking a bribe.
* ShoutOut: 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 arrestation 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.
* TooDumbToLive: After one of the judges suspects Homer of helping Lisa with her essay she asks him whether 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!
* UsefulNotes/ThomasJefferson: Lisa visits his monument.
