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 had PMS. The
elves 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?”
