This is some extreme geekery right here. By placing Yoda on top of the Christmas tree, it allows nerds to worship their Jedi Master from below as is only proper, because you are just a padawan with a closet full of collectibles, while Yoda is…Yoda.
In the hierarchy of Star Wars Christmas tree decorating Yoda must be on top, just as Jar-Jar must be at the bottom. Forget the usual glowing star. Yoda has a light up LED lightsaber. Only $39.99 nerd points.
