What exactly is this Elf on the Shelf and why are people going so crazy for it? Well, the concept behind the weird little red-clad elf is that he is actually one of Santa Claus’ little helpers. He hangs out in your house during the day and then reports back to Santa Claus nightly to let him know who’s been naughty and who’s been nice. Parents move the elf a little bit every night so that kids think he’s been leaving at night to tell Santa exactly what they’ve been doing. When you think about it, it’s kind of a strange way to control your children’s behavior by making them think they’re being watched by a magical little creature.Ethics aside, some people have started having some fun with their elves. The elf, who has large bright eyes and rosy cheeks, is so innocent in appearance that he almost looks creepy. This makes him perfect for pranks. So what if he terrifies the kids? They’ll probably behave better out of fear than they would out of a need to please Santa. They already know they’re not getting coal no matter how rascally they might be.

1. How the Grinch got Operated On

Everyone’s favorite furry green Christmas pest may have stolen Christmas, but these elves got their revenge when they stole his innards. A Grinch kidney sells for good money on the red and green market these days.

2. Santa brought them a new plasma screen TV for Christmas.

The elf was none too happy when the family he was living with got a new flat-screen TV and started ignoring him, so he decided it was hammer time. He also arranged a pleasant little message for them using some quaint decorative lettered Christmas cubes.

3. How many points is this worth?

After sitting down for a nice game of family Scrabble, this elf got out of hand and ruined things with his dirty mind. It’s still better than the time he convinced the family to play strip poker.

4. Elves love sugary treats.

This elf climbed down from his shelf while his family was sleeping and got into the snack drawer. He then proceeded to binge until he was almost as fat as Santa Claus himself. If your child has a sweet tooth, try pranking them in a similar fashion to teach them about the dangers of overindulgence.
