I didn’t Elf, until they started selling them last year at Costco (which I think must have really boosted its popularity). It’s a new-ish family tradition based on a children’s book and, of course, TV movie.
Elf On The Shelf is an Elf doll you buy, name, and place on a shelf in your house. He “watches” your children all day, and while they sleep at night he flies back to report their behavior to Santa. But, he can be pretty silly upon his return the next morning.
Our Elf toilet papered the bathroom. My friend’s son found their Elf in the freezer eating ice cream. I saw a pic on Facebook of someone’s Elf bathing in mini marshmallows in their bathroom sink.
Got an Elf and don’t know where to start? Google “Elf on the shelf ideas”, and at least a hundred images come up. Or do a search on Pinterest for Elf on the Shelf. It’s crazy town.
