After Martin beats her to the punch using her first idea, Marie Curie, Lisa changes her speech to one on Homer, in which, among other things, she remembers when she was sent off by him during a school soccer game.
Homer admits to Bart that it is hard to turn down the bribes, but knowing that Lisa chose him as her hero, he has no other choice.
The betrayed militiamen are just about to kill Homer when Marge begs them in fluent Portuguese (which she has been attempting to learn throughout the episode) to forgive him.
The Simpsons are later seen in the middle of the marsh lands and rivers of the Amazon enjoying all the beauty of the nature as Homer admires a clearing of a section of rainforest in order to make way for a Krusty Burger.
For one, it's the Simpsons' first trip back to Brazil since the infamous season 13 episode 'Blame It on Lisa' which angered the Brazilian tourist board so badly that there was a lawsuit in the works.
Throw in some of the old reliable Homer/Lisa relationship dynamic (ever the most dramatically evocative on the show), and all the pieces were there to assemble a memorable episode.
For one, Kearney placing an 'admire me' note on Homer's back (instead of the usual 'kick me' sign) during Lisa's speech was nice touch.
[5] As one of a number of episodes that were referenced when Donald Trump won the 2016 United States presidential election, this episode is notable for predicting that Brazil would lose to Germany during the 2014 FIFA World Cup, although it happened during the semifinals of said tournament and by a result of 7 goals to 1, not in the final 2–0.
