A lot of my friends use an Elf on the Shelf to promote good behavior in the weeks before Christmas. Like their kids will quit acting up for fear the elf will tell Santa.
Sure, it’s a classic fear tactic, I get it, but wouldn’t it be more effective if the kids were really scared?
Like, what about, instead of elf, they used a goat-horned demon with a foot long tongue carrying rusty chains and bells, wandering the town and wailing for the souls of naughty children?
I think that would do it.
