Get into the Christmas Spirit with this Awesome Video

Mariah Carey, diva-extraordinaire, stopped by Late Night with Jimmy Fallon yesterday. What happened was pure Christmas magic!

In this completely adorable rendition of "All I Want for Christmas is You," Mariah sings the tune while Jimmy and The Roots play toy instruments as back up. There's even a kid's choir! It's enough to make any Grinch's heart melt.

WE HAVE KAZOO, PEOPLE. Jimmy Fallon on a kazoo. It's amazing. And what about that kid in the sock monkey hat? Too cute for words!

I'm quitting writing now, as I've got to get back to watching this on repeat, so... Merry Christmas!
