Watch: Conan and Zooey Deschanel perform "Have Yourself A Merry Little Christmas"

To celebrate the forthcoming exchange of kisses and gifts, Zooey Deschanel threw on her favorite Ten Commandments dress and headed down to Conan's studio for a performance of "Have Yourself A Merry Little Christmas." M. Ward, the other guy from She & Him, was also there, and Conan naturally accompanied them both on guitar. It's pretty damn cute.

It would have been a lot more enjoyable if I wasn't yelling "Do Elf, do Elf!" at the screen the whole time, but much like Yom Kippur, Christmas is all about forgiving.
