Perhaps your children have been expressing some doubt about the true powers of the Elf on the Shelf. With just a couple of days remaining until Christmas arrives, if the so-called myth needs some reinforcing in your house, just show the kids these nine videos. Some parents go to great lengths to capture 'proof' that the elves really do move while kids are asleep. And herewith, we provide you with all the airtight evidence you'll need to close the case once and for all. Also, if you just need some amusement this holiday season, click through and watch. Some of the videos are surprisingly good, all are entertaining -- and not one of them uses special effects of any kind (wink-wink). Merry Christmas!
