Incidentally, Baby it's cold outside is one of my favourite wintertime songs. I think that Lady Gaga and Joseph Gordon Levitt nailed it this year in the Muppet Christmas special.
I also love the She and Him version with Zooey Deschanel. Seriously, can that girl be any cooler?
If you haven't discovered it yet, check out Zooey Deschanel and her amaze balls singing and friendship with Joseph Gordon Levitt. Here's a New Year's song for you - Merry Christmas!
