OK, fortunately I am not familiar with this song. I say 'fortunately' because I think it is total schlock and makes me want to punch something. For reference, I am talking about "Christmas Shoes," the original version you can hear at this link, a video starring Rob Lowe, of all people.
I know that Patton Oswalt's blistering and hilarious commentary on the song have been around for awhile, and this version with animation has been posted for a couple of years now - but I just ran across it. This really matches my attitude this time of year. Great stuff!
