Neil Gaiman appears on The Simpsons

So Neil Gaiman's gone yellow . After winning the Newbery medal, the Carnegie award, as many Hugos as you can shake a stick at and – of course – the Nax Und Moritz Award for Best Foreign Writer , on Sunday he'll finally win the only literary award that really matters: an appearance on The Simpsons . Gaiman's bad American accent – which he's careful to point out was called for in the script – puts him in the most august literary company , along with John Updike, Gore Vidal, Thomas Pynchon and, erm, Mitch Albom . But who is the author you'd most like to see in Springfield?
