It's been a busy day. I've been catching waves, pop-and-lockin' and spinning on my head like America's Best Dance Crew. Man, am I exhausted. Not really, it's just that Elf Yourself is here again, and I never can resist. Who can? According to OfficeMax stats, there are 378 million people in 50 countries just like me who can't get enough of plastering our photos on elves and watching them dance. (New this year: surf dance and '80s remix!) Because this isn't just about goodwill, the marketer will sell you a video of your rump-shaking alter ego, along with "gift items" like mouse pads, coffee mugs and puzzles. (Seriously, only Mom wants a present like this.) There's a game-filled Facebook page called Elfmas Town, where you can get swag and discounts. And just to stay top-of-mind during the holidays, OfficeMax will send 100 elves to the New York Stock Exchange on Nov. 23 to ring the closing bell and stock a Macy's Thanksgiving Day Parade float (dubbed "Elves Raise the Roof"). The viral blockbuster/marketing campaign is five years old now, but with little refreshers and add-ons, it seems as fresh as ever. Or maybe I'm just easily amused by a computer-generated version of me doing the worm. At least I'm not alone.
