Often considered one of the creepiest Sit Coms ever made, The League of Gentlemen is rife with examples. Spoilers below.
- Papa Lazarou. Everything about him. Especially in the Christmas Special. He didn't wind up as the page image for the Nightmare Fuel Live-Action TV page for nothing.
- The Christmas Special also manages to turn Herr Lipp (normally a mid case of Paranoia Fuel) into a full-on terror, mostly through excellent camera work.
- Plus there was the creepy, masked cult who used voodoo dolls and made one-sided deals.
- And last but not least 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 twin daughters, Chloe and Radclyffe. Their Establishing Character Moment - involving 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, incestuous Corrupt Hick Serial Killers, as well as the implied metamorphosis of their son from a normal human being into a monstrous ogre-like creature that lives in the attic. Not something you expect to see on a Sitcom.
- 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. 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 the movie, if at any point you stop writing about a fictional world, 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.
- "We didn't cut their faces off!"
- The photobooth from the 2017 series. Everyone who goes in there vanishes down some sort of shaft once they have their picture taken. It's in the last episode that we finally learn what it is:
Papa Lazarou: It's a wife mine now!
- Pop is probably the most unnerving character in the whole series. A violent, perverted Greek drunkard who abuses his two sons, sexually harrassess the girlfriend of his older son Al, goes out of his way to frighten the two tennants he has staying in a flat he owns and even films the people in that flat without their knowledge. He returns in the 2017 series after being away for over a decade to find that Al and his wife have told their two daughters that Pop died. He's back to his old creepy ways with his own granddaughters, giving them skimpy underwear as "gifts" while Al can only standby and do nothing out of fear for his father. This makes it hard to feel sorry for Pop when his other son Richie murders him when the two finally meet again.
