The Simpson's annual holiday special (We're up to "Treehouse of Horror XXIII" now) is set to air in just six short weeks, and TVLine has the inside scoop on several of the episode's highlights. They include a time-traveler Bart preventing Marge and Homer from tying the knot (with Jon Lovitz voicing Marge's high school sweetheart), a mini black hole in Springfield in honor of the recent "discovery" of the hipster-confounding Higgs boson, and ruminations on the Mayan prophecy that the world will end sometime between now and December 31, 2012.
