We've all been their before. Listening to our music in public and nodding our head, tapping our toes, or maybe even a little air guitar. Then we see someone looking at us and mortification ensues. Youtuber, PrestonLeatherman, takes those inhibitions we usually feel and throws them out the window with a lively number to Mariah Carey's classic "All I Want For Christmas Is You!"

His tacky Christmas sweater makes this video all the better.
