The Simpsons go to Brazil to find a lost orphan after Lisa confesses that she ran up the phone bill with calls to her sponsored orphan.
* [[BannedInChina Banned in Brazil]] and BannedEpisode: The Brazilian government was mad over the show's depiction of the country and had it banned after only two airings. When FOX released season 13 of the show to Brazil, there was still contention on whether or not the episode can be shown on the Brazilian DVD version. The episode did end up being released on DVD in Brazil (compare with Japan and "Thirty Minutes Over Tokyo," in which the episode was so insulting to Japanese culture that it was banned from airing on TV ''and'' being released on DVD, meaning, in Japan, the last episode on the season 10 DVD set is "They Saved Lisa's Brain"). It probably helped that the showrunners did apologize for it and meant the jokes only in jest.
* TheCapitalOfBrazilIsBuenosAires: Quite some Brazilian stereotypes are shown here.
* ComicallyMissingThePoint: When Homer entered an unlicensed taxi, the driver pulled a gun and told him it was an abduction. Homer then asked if that meant he wouldn't have to pay for the ride.
* ConvenientlyAnOrphan: Renaldo said he had the money to help the Simpsons because he didn't have parents to take it from him, like so many child stars in America do.
* CriticalResearchFailure: The dance instructor claims to be thinking of a new sexy dance, even sexier than the Lambada or the Macarena. While the Lambada was indeed Portuguese the Macarena was sung by a Spanish group. The confusion probably stems from their group name, Los del Rio, which doesn't refer to Rio de Janeiro, but to the Spanish word for "river".
* FanDisservice: Homer's fat, lumpy butt in a Brazilian Speedo (which rides into his ass crack), which causes one woman to make a cross sign with her fingers, another to blind herself by throwing sand in her eyes, and another to stick a jellyfish on her head.
* ItsAlwaysMardiGrasInNewOrleans: While the Simpsons are in Rio it's carnival. Of course, it is!
* LeftTheBackgroundMusicOn: During the cable car ride, Marge comments that the tension is killing her, so Bart switches the music player in the cable car to another theme, but Marge says that [[SoundtrackDissonance it's making light of the situation]], so they switch to another theme which satisfies Marge.
* MyCountryTisOfTheeThatISting: Homer wears a "Try to Stop Us" T-shirt with Uncle Sam devouring the world on it.
* ShoutOut: Homer asked [[TheFlyingNun a nun to fly carrying him]].
* ShownTheirWork: For all of their flaws on Brazilian culture and life, the writers ''did'' get one thing right: Portuguese is the official language of Brazil, not Spanish (in fact, Brazil is one of four South American countries in which Spanish is not the main language. The others are Guyana[[note]]whose official language is English, though Spanish, Portuguese, and a lot of indigenous languages are recognized and spoken, and Guyanese Creole is considered the country's national language[[/note]], Suriname[[note]]whose official language is Dutch[[/note]] and French Guiana[[note]]whose official language is French, obviously[[/note]]).
* StockholmSyndrome: Homer bonds with his kidnappers, even compiling a scrapbook with them.
* SuspiciouslySimilarSubstitute: A Brazilian waiter looks like the Costington employee who always says "Yeeeesssssssss" (only here, he says "Siiiiiiiimmmmmmmmm," which is Portuguese for "Yes").
* WhereTheHellIsSpringfield: The orphan Lisa sponsored couldn't send her a letter because he didn't know which state Springfield was located.
* WhyDoYouKeepChangingJobs: Linsday Naegle was asked that. Her answer: she's a sexual predator.
