Christmas episodes have become a time-honoured television tradition. Many shows bring on the good tidings, but only some manage to really separate themselves from the pack. Just as every seasonal tune can't be a hit, only the best holiday episodes stand out in our memories. We can only watch characters trot through their show's version of It's a Wonderful Life so many times. An extra "bah humbug" to any series that merely regurgitates A Christmas Carol.
