The Simpsons have been on the air for more than 20 years, so maybe it's not so surprising that of the hundreds of episodes, at least one would inspire a nation to threaten FOX with a lawsuit. In 2002's "Blame It on Lisa," the family heads to Rio de Janeiro, where all sorts of Latin American stereotypes play out and the family has a less than idyllic trip. Homer gets kidnapped by a cab driver, and Bart watches a children's show called "Teleboobies" (that's before he's swallowed by a snake, of course). The episode hadn't even aired abroad before Rio's tourism board said it would hurt efforts to bring in visitors and threatened legal action.
Said executive producer James Brooks: "We apologize to the lovely city and people of Rio de Janeiro, and if that doesn't settle the issue, Homer Simpson offers to take on the President of Brazil on Fox's Celebrity Boxing."
