It happens once a year, each December. There are trees, angels, snowmen, carols, wacky hijinks, and lots of joy to spread around. We're talking, of course, about the Doctor Who Christmas Special!
Prepare yourself (and your tree) for the Christmas Special with this ThinkGeek-exclusive TARDIS ornament. It lights up, with the colors red, yellow, green, blue, and violet cycling through the phone box's windows. Hang one on your tree or ornament stand, and maybe you'll get a visit from the Doctor instead of Santa this year!
