One particular Christmas a long time ago, Santa was getting ready for his annual trip... but there were problems everywhere.
Four of his elves got sick, and the trainee elves did not produce the toys as fast as the regular ones, so Santa was beginning to feel the pressure of being behind schedule. Then, Mrs. Claus told him that her Mom was coming to visit.
This stressed Santa even more. Then when he went to harness the Reindeer, he found three of them were about to give birth and two had jumped the fence and were out, heaven knows where. More Stress.
Then when he began to load the sleigh one of the boards cracked and the toy bag fell to the ground, and scattered the toys.
So, frustrated, Santa went back into the house for a cup of coffee and a shot of whiskey. When he went to the cupboard, he discovered that the elves had hidden the liquor and there was nothing to drink.
In his frustration, he accidentally dropped the coffee pot and it broke into hundreds of little pieces all over the kitchen floor.
He went to get the broom and found that mice had eaten the straw it was made from. Just then, the doorbell rang and Santa cussed his way to the door. He opened the door and there was a little angel with a great big Christmas Tree.
The angel said, very cheerfully, "Merry Christmas Santa. Isn't it just a lovely day? I have a beautiful tree for you. Isn't it just a lovely tree? Where would you like me to stick it?"
Thus began the tradition of the little angel on top of the Christmas tree.
