Lumps of coal in stockings just isn’t as much of a viable threat as it
used to be. The naughty list gets bigger and bigger every year. Santa
was forced to bring in an outside consultant to evaluate his current
nice/naughty gift/coal system. Eventually with the help of yours truly,
The Warlock, we were able to conclude that certain problem adults were
most certainly the cause of increasing global naughtiness, and a more
strict punishment should be in order to disrupt their negative influence
over the holiday. Maybe after a few years helping pull the sleigh they
would better appreciate the true meaning of the holiday.

If not, the elves were already working on plans to build a larger stable for a few new reindeer…
