Often considered one of the creepiest {{Sit Com}}s ever made, ''TheLeagueOfGentlemen'' is rife with examples. Spoilers below.

----
* '''THE ENTIRE DAMN SHOW!!!!'''
* Papa Lazarou. Everything about him. [[BadSanta Especially]] in the ChristmasSpecial.
* The ChristmasSpecial also manages to turn Herr Lipp (normally a mid case of ParanoiaFuel) into a full-on terror, mostly through excellent camera work. Plus there was the creepy, masked {{cult}} and the Victorian curse. Who ever thought shadow puppets of a monkey screwing an elephant could be so scary?
* Harvey "Toadface" Denton becomes increasingly sinister and monstrous over the series, and yet he's got nothing on his [[CreepyTwins twin]] [[CreepyChild daughters]], Chloe and Radclyffe. Their EstablishingCharacterMoment - involving [[ScaryScarecrows a man trapped inside a scarecrow]] - is particularly well-remembered, as is their alarming pleasure at killing their father's beloved toads.
** As well as locking their parents in a room in the basement. It's implied that they never let them out again as they don't appear in the show afterwards.
* Edward and Tubbs, a pair of incredibly hideous, [[VillainousIncest incestuous]] CorruptHick {{Serial Killer}}s, as well as the implied metamorphosis of their son from a normal human being into a [[BerthaInTheAttic monstrous ogre-like creature that lives in the attic]]. Not something you expect to see on a SitCom.
* [[TheButcher Hilary Briss]] is mildly creepy all by himself, but the mysterious meats he sells (and the bizarre, dreamlike scene of him purchasing them from a dealer) are absolutely horrific.
** The creators were asked if his meat was human flesh... Their answer? No. [[spoiler: It's so much worse than that.]]
* The Nosebleed Plague. Even Papa Lazarou was creeped out by that.
* The scene in the second series where Pauline and Ross wrestle features a moment where Pauline forces Ross onto a table and tries to stab him with a pen, all with a terrifyingly feral look on her face. This was immediately followed by Ross biting down on her breast ''hard'' with a sickening ''crunch!''
* According to [[BigDamnMovie the movie]], if at any point you stop writing about a fictional world, [[spoiler:it is destroyed by a fiery hail of meteors--so, essentially, any time a series ends you're dooming not just your leads but dozens of incidental characters and extras, to say nothing of the countless people who ''implicitly'' populate the work's world, all of whom actually exist on another plane.]]
