This holiday season, as with all holiday seasons before it, Santa was fast at work making his list and checking it twice. When it comes to list making, he is the master. Can you imagine how difficult it must be to be responsible for and track each person’s naughty or nice status and cross-reference it with what he or she wants? Even with the most advanced Excel skills, this would be a daunting task. But each year that jolly old elf manages to do it and, presumably, maintains everything he needs to in his own life.
