Excuse me, sir? You have a TIE-Fighter on your head.
This came to my attention via StarWars.com, who found it originally on Great White Snark. There's no info to be found on the construction of the TIE-Fighter helmet or its wearer (or the guy sneaking a peek from around the corner), but its one of the more amusing Star Wars costumes I've seen.
It's like the world's nerdiest hat.
