  • T'was December 25th and Santa's sleigh spiraled towards Earth like a lamed paper airplane released by the clumsy hand of a child. It tore through the moonlit clouds and was battered by illimitable volleys of flak. Each round hissed by the crimson sled, exploding with a thunderous pulse that left the sky reverberating and stained with an ominous dark streak.

    "Louis!" Santa bellowed trying to regain control of his damaged craft that only had three remaining reindeer; Prancer, Vixen, and Comet. Louis, as he was called, raised his head from between the bench and, began to acknowledge Santa but was interrupted by a sudden jerk that left him unconscious after his temple became acquainted with the bench corner. And, abruptly, the sleigh had one less engine.

    A projectile quartered itself into the belly of Prancer. His abdomen ruptured and out spewed rosy innards. A mist of blood was smeared onto the front of the sleigh,ugg boots sale, and,Ugg Pas Cher, subsequently, it gave color to Santa's facial hair. The body of the ill-fated reindeer had been blown loose from its harness. It silently fell out of site into the portentous flak clouds below.

    "Damn it!" Santa shouted, furiously slamming his fists on the sleigh's railing. He leaned over to look at Louis, "Louis!" he barked almost inaudibly through the cadent torrent of violence and war. "Louis," the Claus repeated softer leaning over to nudge the small elf's body. Slowly, the elf turned and looked at Santa. The bearded gift giver nodded and said nothing. His face turned stoic as he broke eye contact and began staring towards the two remaining engines; their muscular legs and arses quivering with fatigue.

He noticed this,UGG Boots 5119 Kinghtsbridge, took a deep breath, and withdrew a frighteningly large hunting knife from the depths his coat, and sliced the reins.

    The sleigh was now without engines and it began to descend more quickly than before into uncertainty. The sleigh went down at an angle that produced an acute howl as it sped through the air like mortar making its decent onto a relatively unsuspecting fortification. The same angle had Santa penned in his position,moncler wien, unable to move. It was as if he was stricken with some sort of catatonia that strangely left him capable of vocalizing. And vocalizing he did.

    "Louis!" Santa hollered over the combined howling of the sleigh and deafening thuds of flak, "Grab on to something, it's going to be a mess!" Santa finished, his voice going hoarse.

    "WHAT'S HAPPENING BOSS?" the elf squealed inaudibly grabbing on to Santa's leg, tightly, right as the sleigh collided into a strip of tin shanties.
