Jimmy Fallon, Mariah Carey and The Roots Perform Best ‘All I Want For Christmas’ Rendition Ever

If only Jimmy Fallon's show was just music. Here is probably the best rendition of 'All I Want for Christmas Is You' ever, performed by Mariah Carey, Jimmy Fallon, and the Roots on toy instruments. Oh! Plus a chorus of jack-in-the-box kids wearing winter hats. It has maybe gotten us more into the Christmas spirit than even DMX's version of 'Rudolph the Red-Nosed Reindeer.' Enjoy, we have to go spend all of our money on presents now.
