Tomorrow is "Star Wars Day" . . . all because some Star Wars nerd heard "May the Fourth" a few years ago, and made him think of the line, "May the force be with you."

And there's a new parody video on the official "Star Wars" YouTube page to celebrate it, called "Star Wars Day Attack Ad".

It's done exactly like a political ad, but it's, quote, "Paid for by the Emperor's Committee to Destroy May the Fourth" . . . and it talks about how Jedi's use the Force for evil things, like mind control.
