Altho it wasn't, perhaps, a classic for the ages, Sunday night's Simpsons did have a bunch of just killer stuff. Including Jack Black as a hipster comic book guy who sang a Korean pop cover of "What's New, Pussycat?" and a nice Tin Tin homage and Dan Clowes, Alan Moore and Art Speigelman as themselves (and superhero versions of themselves). Moore in particular was one of the better artist cameos they've had (right up there with Jasper "yoink" Johns).
