"...a crossover one with… Adventure Time. (Simpsons supervising director, Mike Anderson — who is a big fan of the animated Cartoon Network show — pitched the bit and wound up directing it.) The theme song to Adventure Time gets Simpson-ized to “Simpsons Time,” and will be sung by the show’s creator, Pendleton Ward." via EW
-Adventure Time Comics #1 comes out this week. Instead of the continuity of stories it's all about shorts from different artists.
