Watch: 41-Year-Old Mariah Carey Macks On 17-Year-Old Justin Bieber In Christmas Video

One could play a game with this video.

In this update of Mariah Carey's Christmas favorite "All I Want For Christmas Is You," who would you say gets luckier?

Is it Carey herself, who at 41 years old, can thank Jenny Craig for looking better than she has in years dropping 70 pounds after giving birth to twins?

Could it be Justin Bieber? After all, the goofy-looking doofus was apparently blessed with the logic here that if a 20-year-old gold-digger sets out to torch your life so that she can collect a fat one-time payday, the only path to happiness is to make nice in Santa's sleigh with mother of all mammiferous mannequin-MILFs named Mariah?

Maybe it's Nintendo and Macy's, for the festive platform for flinging their product-placement in our faces like crazed chimps fling their Yule logs at unsuspecting zoo patrons.

My pick? The screaming throngs that Bieber apparently flings freebie Nintendo 3D2 handheld consoles. That goes double if he threw in a couple copies of "The Legend Of Zelda: Skyward Sword."

Still, it's a fun video, featuring a mannequin Mariah coming to life and showing that if someone ever remakes "Mannequin" and sees this video, Kim Cattrall's second most-enduring legacy is toast.

So here's one more Christmas gift, from us to you: one more reason we can just about guarantee you will want to light Justin Bieber on fire.
