The Looney Tunes Show/Nightmare Fuel

"Bugs: You're the reason I always keep my shades down!"
 * In "Devil Dog", Taz, in this version, is very monstrous and has a murderous rage. Oh god, the evil red eyes and the entire scene with him nearly eating Sylvester and Tweety, it can practically make one wet herself. Sylvester fleeing down that dark hallway with a look of sheer terror on his face (not played for laughs terror-- REAL terror), might be the scariest part of that sequence.
 * Lola's stalker-centric song, "We are In Love" was just filled to the brim with Yandere undertones, and if that wasn't enough, at one point, there is a shot of her standing outside Bugs' house in the middle of a lightning storm, silhouetted, with an eerie Slasher Smile the only thing seen in between the lightning strikes.


 * The episode where Daffy thinks that Porky is a serial killer. It does have a rational explanation, but the leadup is genuinely unsettling.
 * "PUT DOWN THE STAPLER OR I'LL WRITE OVER THE PIG'S FACE!!!!!"
