It's Beginning to Look a Lot Like Zombies!: A Book of Zombie Christmas Carols by Michael P. Spradlin
This book takes over two dozen of our most beloved Christmas carols and shreds them limb from limb, rewriting them from a zombie's point-of-view. Tiny tots' eyes are no longer aglow - they're in a bowl. And Mommy's not kissing Santa under the mistletoe - she's chewing his face. Nobody - not Rudolph, Old Saint Nick, or even those three Wise Guys who traveled afar - is spared when the undead come knocking.
