Wally: I discovered a way to bend light around an object to form a cloak of invisibility. We'll make billions selling it to the military. I'll be testing it over the next several months. You'll know it's working if you never see me in the office. During that time, don't sit in any empty-looking chairs unless you first shout my name and clap. WHAT'S THAT OVER THERE?! Boss: What? I don't see anything. Wally; How do you like it so far?
