 Outside Mr. Burns ' manor , Smithers is standing on a ladder , trying to put up a small orange bat decoration on a weather vane . He slips on the ladder , grabs on an electric cord and slides down into an electricity box and gets zapped . A tower from Mr. Burns ' mansion breaks in half , damaging a mausoleum , which opens up four caskets which in turn reveal three skeletons which all resemble Mr. Burns , dressed in various costumes . Later , we see the Simpsons dressed up in costumes , with Homer as Fred Flintstone , Marge as Wilma Flintstone , Lisa and Maggie as conjoined twins , and Bart as a hobo walking up to the mansion ( with Bart and Lisa complaining that Flanders gave them toothpaste instead of candy ) . The family sees the building and caskets on fire , and screams in terror . They run out the gate , which as it closes , has its bars slice the family . The slices of the Simpsons continue to scream and run away . Mr. Burns , delighted , pats the orange bat as it comes to life and flies into the screen , revealing the title , “ The Simpsons Halloween Special XII " .
