"Believe in the power of magic...Or I'll kill you..."
MST3K, episode 1003: Merlins Shop Of Mystical Wonders
I was browsing youtube when I came across this gem. It's an old low-budget Santa Claus movie with all the trappings of the nth level of hell. When MST3K was on the air, they used to call things like this "Good Old-Fashioned Nightmare Fuel". In fact, I believe
this movie was one of those they described as such.
Warnings include creepy children and Santa ho-ho-ho-ing like a rampant psychopath, feel free to enjoy every soul-scarring moment below:

And for the unleaded version:
(I actually found this far more frightening
in it's intended context in part 2)
