Do you celebrate Sithmas or Trekmas?

Even science fiction fans like to take the time to celebrate Christmas. According to reports, Hallmark's Robby the Robot ornament is flying off the shelves this year. It's not the only sci-fi ornament they are selling this holiday season. They've got a complete line of Star Wars and Star Trek ornaments.

Probably the oddest of the lot is this one from the Trek episode The Menagerie which depicts Capt. Pike in his iron lung, or whatever the heck that box is that he lives in. They've also got a bunch of other genre-related ornaments like this Twilight Zone TV and even an old arcade box from the 80s.

None of this is new. Hallmark has been doing this for years and there is a long line of scif-fi ornaments out there, many of which have become valuable to collectors.

I must confess that I have some Star Wars ornaments on my tree, but I bought them for my kids. That's my story and I'm sticking to it. They aren't the pricey Hallmark ones, though, but some other random characters that I picked up at a Canadian Tire store, of all places.

I don't remember Christmas ever having been mentioned in the Star Trek universe, although some fan with a long memory can probably tell me if it was. Do fans of the show celebrate Trekmas? Or how about Star Wars fans? Is their seasonal holiday Sithmas?
