Finally! This Sunday night (8PM/7C) is the long-awaited airing of The Simpsons episode featuring Daniel Clowes, Art Spiegelman, Alan Moore and Jack Black. Reportedly, the episode finds Jack Black's character opening "Coolsville," a hipster comic shop that threatens the Comic Book Guy and Android's Dungeon. How Clowes, Spiegelman and Moore factor in we can only guess, but can't wait to find out. Set those Tivos early.
