Where the old tradition of putting an angel on top of a Christmas tree came from:

Santa was having a bad day. Mrs Claus was nagging and PMS. The dwarves were working slowly due to rotating strikes and picket lines. There were serious assembly problems. Claus's daughter required expensive dental care after biting down on her tongue ring. Rudolf was getting old and stodgy, and was having elimination problems. And Claus himself put his back out working out at the local Fitness World. In the midst of all this a shimmering angel arrived one evening with a lovely tree. As Claus answered the door, frowning and muttering, the angel smiled and said "Merry Christmas, Santa! Here's your tree. Where do you want me to stick it?"
