If you've seen the original 'Star Wars' movies, you'll know that Darth Vader was a bad guy. He ruled through fear as opposed to love, and had no qualms killing people on his own side if they angered him.
Maybe these storm troopers have developed Stockholm Syndrome, because they look pretty pleased to see him. It's a very funny picture, but we have a question. Who allowed someone to walk through airport security dressed as Darth Vader? He really must have the force on his side!
