Fans were also treated to a segment from this fall’s annual “Treehouse of Horror” episode called “The Greatest Story Ever Holed,” in which the Simpsons adopt a mini-black hole that is growing more powerful. Let’s just say that the hole has an interesting reaction to Bart feeding it his math homework. And what happens when Comic Book Guy inserts Disney’s The Black Hole in the black hole? These are the great mysteries of the universe that you will unlock in a few months.
