The TARDIS is as much a part of Christmas as turkey, mince pies, and mulled wine, and former "Doctor Who" showrunner Steven Moffat certainly knows his way around a festive adventure. This year's holiday offering, "Joy to the World", is the writer's ninth, and it comes with all the trimmings you'd expect.

It’s not that Doctor Who’s festive episodes can’t be memorable; “The Husbands of River Song,” “A Christmas Carol,” “The Runaway Bride,” and more beg to differ. But I know it’s a holiday tradition in the U.

The Doctor is back for another holiday special. We'll show you where to watch the Doctor Who Christmas Special around the globe.
