Nightmare Fuel: A Christmas Story
Scut Farkus: with yellow eyes, so help me God! When he first shows up, he's laughing maniacally and chasing Ralphie, Flick and Schwartz.
The scary department store Santa going into slow motion, with the music in the background slowing down to match.
Aided and abetted by the 1st Person POV fisheye camera shots as Ralphie goes up to see him. We see a distorted and fast view of a very bitter Santa (with lurid red nose) and two mean elves! HO... HO... HO.....
