It was Christmas eve in Lapland and Santa was having a most horrendous day. The fence in the reindeer field had broken and 3 of the reindeer had wandered off. The elves were refusing to work as the heater in the workshop had broken down, and Mrs Santa was in a foul mood as she had overcooked the turkey and ruined it. Just then there was a knock at the door, and when Santa opened it there was a fairy, holding a christmas tree. "Here's the tree you ordered, Santa, where shall I stick it?" And that, my friend is why there is always a fairy on the top of the christmas tree.
