Ned Flanders is assuming the role of serial killer Dexter Morgan in the clip, which gives a Springfield makeover to the crime drama series' opening credits.
For this year's Halloween, "The Simpsons" will take a jab at "Dexter". A sneak peek to the episode, which was presented at Comic-Con last weekend, has now landed online via Entertainment Weekly although the annual festive event is still months away.
The clip presents a Springfield version of the Showtime series' opening credits complete with the theme song. Meanwhile, chanelling his inner serial killer Dexter Morgan is Ned Flanders who is seen doing his daily routines before he throws away his victim from a harbor.
Called "Treehouse of Horror XXII", the episode will air on October 30. It will see the devout Christian neighbor to Homer Simpson believing that the big guy upstairs is instructing him to murder various residents of the town.
