These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: The Simpsons S 21 E 4 Treehouse Of Horror XX
Nightmare Fuel: Being a Treehouse of Horror episode, there's bound to be moments of this, such as Muncher Krusty attacking the camera and the scene of Homer impaled on the distiller.
Squick: The burgers that start off the Muncher apocalypse are made from beef that is given to other cows and then repurposed into the burgers. Becomes more of Squick when it's referred to as the "Mad Cow" burger.
Homer on the distiller, especially when he's wrinkly from being drained of blood
