Simon's chief success with Homer was adding a vulnerability and heart that makes his stupidity and self-destruction far more tolerable: he's a fool rather than just an idiot. But The Simpsons was never going to be a straight drama with cartoons: it might be intelligent and aspire to actually telling moral lessons, but some of the finest moments come when the writers took away Homer's limitations. That was the case for the beautifully stupid, almost nightmarish romp in the Land Of Chocolate, which was wholly Simon's creation and remains brilliantly funny.
