YMMV: The Simpsons S 4 E 2 A Streetcar Named Marge
Dude, Not Funny!: New Orleans residents at the time were not pleased about the opening song number describing New Orleans being a Den of Iniquity and the home to "pirates, drunks, and whores". The writers stated that this was a reference to the Sweeney Todd song "No Place Like London" which gives unflattering descriptions of London. This was later lampshaded in one of Bart's chalkboard gags.
It should be noted that the outrage came when the lyrics to the song somehow got leaked before the episode aired. Once it was seen and heard in context the people simmered down.
Harsher in Hindsight: Following Hurricane Katrina, the callous opening song number about New Orleans became more cruel, which is why the BBC had to issue an apology for airing this episode around the time that Hurricane Katrina and its destructive path across New Orleans was in the news and fresh in everyone's minds.
