What is this odd KFC sandwich, and should you be scared of it?

KFC's new Double Down sandwich raises a lot of questions: Is a sandwich truly a sandwich if it contains no bread? How do you eat this without getting your hands all greasy? Who's it for? Atkins fans? Gastronomic daredevils? Does this thing—which contains two fried chicken fillets, two slices of cheese and two strips of bacon—really clock in at fewer than 600 calories, as KFC claims? Consumers in Providence, R.I., and Omaha, Neb., may be mulling these questions, since those are the only two places you can buy the item right now. But KFC appears to be, uh, greasing the wheels for a national entry. There's a TV ad from Draftfcb, Chicago, that shows a bunch of guys complaining in helium voices that they're tired of chicken sandwiches that have a big bun and little in the way of chicken. Then the Double Down comes along, and they start speaking normally. Despite its limited introduction, the sandwich has gotten considerable buzz. A YouTube version of the Draftfcb ad has gotten more than 180,000 views, and a Fox News report has garnered more than 80,000. That anchor couldn't help musing that this may be the best thing since sliced bread.
