I have a coworker who owns a Darth Vader costume. If you ask him really nicely, he might dress up as Darth Vader to scare your kids. He’s proud enough to own that costume that he keeps a picture of himself in it on his desk.
Someone–I forget who–had the idea this past week that his cubicle neighbor ought to get a Chewbacca the Wookie suit. Because nothing goes with Darth Vader like Chewbacca, right? Several of us even reached for our wallets in anticipation of taking up a collection to fund this Chewbacca suit, and then someone threw out a stipulation–that the two of them need to wear their costumes to work.
For some reason, I still have my copy of the corporate dress code, so I got it out to see if it would be legal to wear Chewbacca and Darth Vader costumes to work.
