Kidding aside, at least when someone asks you: "Who are you?" you won't answer: "I'm Batman!".

No, I can say, "I'm an engineer. Run."

It can be quite amusing at security check areas such as in airports. It gives them something to do, I guess, aside from being intrusive and impolite. My laptop bag gives them fits as well, it shows up as almost unintelligible noise under the Xray machine.
