I don't watch the Simpsons anymore, so I'm not aware of what they did...care to elaborate?
The episode was set in Italy where Sideshow Bob was hiding.... after it's revealed that he is an American criminal, the Italian police officers pull out a book of famous American criminals and flipped through the pages, each had a picture and a title beneath it...
Page 1: Snake - Invasion di Casa
Page 2: Mayor Quimby - Drink-o Drive-o
Page 3: Peter Griffin - Plagiarismo
Page 4: American Dad (don't know his name) - Plagiarismo di plagiarismo
and then page 5 was Bob.
