Rudolph's Ears
Christmas was over. Santa and his reindeer finally had a chance to rest. And they deserved it. They had done a good job. Rudolph had a chance to do something he had wanted to do for a long time. He made an appointment with a plastic surgeon because he was so sensitive about his looks.
However it wasn't his glowing proboscis that he wanted changed. He was proud of his
nose and the help he had given Santa because of it. No, he was sensitive about his long ears which were much more prominent than the ears of the average reindeer, or bear for that matter.
So one week after Christmas, he let the good doctor do the pinna reconstructive surgery procedure, and since that time, January 1st has been celebrated as ... New Ears Day.
