The Simpsons
FXX is celebrating Halloween with a special marathon of "The Simpsons" "Treehouse of Horror" episodes, which will air for one week straight leading up to Oct. 31. FOX

Season 27 will mark a historic moment for Fox’s “The Simpsons” as the first family of TV animation will debut its first ever Halloween episode on Oct. 18. Now, the network has released a genuinely spooky, albeit still hilarious, teaser clip to promote the landmark episode.

As many diehard “Simpsons” fans are no doubt already rolling their eyes, it’s worth mentioning that it’s only the first ever Halloween episode of the series in the most technical of ways. Since Season 2, the series has dedicated one episode per season to its “Treehouse of Horror” series. While each of these episodes are Halloween-themed, they’re usually a collection of non-canon short stories presented using “The Simpsons’” characters. According to TV Line, Season 27 will have a “Treehouse of Horror” episode on Oct. 25, but it will also contain a canon episode in which Homer (Dan Castellaneta) tries to protect himself and Lisa (Yeardley Smith) from a group of “vengeful seasonal thugs.” In the clip below, Homer puts the house on lockdown, but, in true Homer fashion, fails to do so without making thing scarier.

Savvy horror movie fans may remember the theme that the oafish Homer whistles to calm himself as the dramatic theme music that first appeared in John Carpenter’s 1978 slasher-film “Halloween.” Ironically, the music tends to play loudest in the film just before its antagonist, Michael Myers, is about to kill someone.

Unfortunately, while the clip is heavy on the laughs and scares, it’s light on the details. For example, fans are left with a mystery as to who these three mysterious Halloween-themed stalkers are. Luckily, the episodes’ official TV Guide synopsis may hold the answers.

“Lisa is frightened at Krustyland Halloween Horror Night, so Homer removes his Everscream Terrors decorations, which leads the now-jobless pop-up employees to seek vengeance on him by robbing the house and forcing him and Lisa to seek refuge in the attic.”

“The Simpsons” first Halloween episode, “Halloween of Horror” will air Oct 18 at 8 p.m. EDT. The 2015 “Treehouse of Horror” will air on Oct. 25 at the same time. Will you be tuning in to both spooky episodes? Comment below or tweet your thoughts to @TylerMcCarthy.
