Looney Tunes/Nightmare Fuel

• The Looney Tunes short "Now Hear This " is a No Dialogue Episode set in a surreal landscape that's apparently a minimalist version of London. It involves a British gentleman getting into all manner of at-times-creepy weirdness upon finding an apparently cursed ear trumpet. Strangely behaved shapes appear inexplicably, accompanied by discordant noises, and at one point the poor bloke is plunged into darkness while being menaced by dozens of mean, staring eyes and floating text reading "PUNK" and "WISE GUY". After abandoning the device in favor of his old one, we promptly find it was Satan's horn.
• The Solid Tin Coyote. Watch at your own expense.
• The Case of the Stuttering Pig.
• Satan's Waitin', in which Sylvester literally goes to hell just for doing what cats do, e.g. chasing Tweety Bird.
• "The Big Snooze" being the most blatant. Lampshaded in three Chuck Jones-directed cartoons: "Scaredy Cat," "Claws For Alarm," and "Jumpin' Jupiter", where Porky takes Sylvester to these scary places to sleep for the night, and only Sylvester can see the scary things just about to happen to Porky...
• "Chow Hound": "And this time, we didn't forget the gravy!"
• "Porky in Wackyland" can be a little too bizarre for some.
• Porky In Egypt (1938): In this scene, Porky's camel Humpty Bumpty starts to hallucinate while in the desert heat.
