I don't have kids. Not having kids makes it so that I don't have to threaten them to be good or "Santa won't come", and means that I don't have to adopt one of the creepiest Christmas traditions I've ever seen.
The Elf on the Shelf is quite possibly one of the creepiest things I have ever seen. Part of this, I am sure, is that the elf looks a little bit too much like a clown for my taste. But, the story behind it is a bit creepy, too.
