One, two, three, fours, finger me some Star Wars. Or, uh...no, that doesn't sound quite right. But everything is better with lightsabers. You could put blasters on your digits, but that would be clumsy and random.
I can't be the first person to think, though, that given the size of the holes in the cardboard displays, the Star Wars Thumb Wrestling set need not only be for thumbs. Ditto the apparently adjustable straps on the sabers.
