From Patrick McGee:
Roger, just read your "Tooth Fairy" review. I thought you'd appreciate this little story.
We have 5 kids (a couple still in the “believe” age group). We've never really pushed the idea of the Tooth Fairy….just went-along with it like we assumed the kids did. I did come up with a novel story that horrifies the little believers and really cracks-up the older kids. I used the plot of the movie Underworld to create a story about the blood feud between Santa (elves) and the Tooth Fairy (fairies).
Santa had a son who fell in love with the Tooth Fairy's daughter. Because Santa could not abide such a mixing of the species, he had the Fairy's daughter killed. The Tooth Fairy responded by killing Santa's son. So began the blood-feud. Elves and Fairies have fought and died by the thousands over the ages. But, most critical, is what happens on Xmas Eve. Should a child be unable to prevent the loss of a tooth on Xmas Eve, it's possible that the Tooth Fairy and Santa end up at that very house at the same time. When this happens, the resulting battle destroys several city blocks.
