The Simpsons is known for its litany of colourful characters, and fans have been entertained by the likes of Homer, Bart, Lisa and Marge for almost quarter of a century. Which is why, when show producer Al Jean revealed earlier this month that one of the yellow denizens of Springfield was to be killed off, it was such big news. "I'll give you a clue that the actor playing the character won an Emmy for playing that character, but I won't say who it is," Jean said.
