Neil Gaiman on The Simpsons

We've mentioned Neil Gaiman a while ago and suddenly Martina pointed out to me this post where the man is coming out of the Marge Simpson Studio where he recorded his part for an upcoming Simpson's episode. I think he's the fourth comic book writer after the brief but epic appearence of Alan Moore, Art Spiegelman and (I think) Daniel Clowes. Can't remember if Stan Lee was ever on The Simpsons but, c'mon on! He's Stan Lee! He makes more cameos than comics nowadays!

And I'm probably forgeting someone else.
