I’ve just learned from Eric Reynolds that Daniel Clowes, Art Spiegelman, and Alan Moore will appear on the October 7 episode of The Simpsons. Sayeth Reynolds:

The plot concerns Comic Book Guy, who gets some competition in Springfield from a new store, “Coolsville Comics & Toys,” run by “hipster” Milo, voiced by Jack Black.

No word yet on whether either of these folks will appear with a bag on his head.
