Tomorrow is the day that Santa Claus was born, and in commemoration of that day, he flies around and gives everyone presents!  You can follow his progress using the NORAD Santa Tracker to see when he'll get to your house... it's way better then tracking your packages with UPS.

OK, I know that's not what Christmas is really about.  To find out what Christmas is really about, watch this.  This isn't the classic version, it's a slightly different interpretation thanks to the folks at Scrubs:

I wish upon all of you the happiest joys of the season.  Remember... its all about Love.  Love of friends, love of family, and the love of Jesus born tomorrow.  Most importantly, you have to give love to get love, so start giving.  The presents are just gravy.
