When four of Santa's elves got sick, the trainee
elves did not produce toys as fast as the regular ones, and Santa began to
feel the pre-Christmas pressure. Then Mrs. Claus told Santa
her Mother was coming to visit, which stressed Santa even more.
When he went to harness the reindeer, he found that
three of them were about to give birth and two others had jumped the
fence and were out, Heaven knows where. Then when he began to load the
sleigh, one of the floorboards cracked, the toy bag fell to the ground
and all the toys were scattered. So, frustrated, Santa went in the
house for a cup of apple cider and a shot of rum.
When he went to the cupboard, he discovered the elves had drank all the
cider and hidden the liquor. In his frustration, he accidentally
dropped the cider jug, and it broke into hundreds of little glass
pieces all over the kitchen floor. He went to get the broom and found
the mice had eaten all the straw off the end of the broom.
Just then the doorbell rang, and irritated Santa marched to the door,
yanked it open, and there stood a little angel with a great big
Christmas tree. The angel said very cheerfully, "Merry Christmas,
Santa. Isn't this a lovely day? I have a beautiful tree for you. Where would
you like me to put it?"
And so began the tradition of the little angel on top of the Christmas tree.
