The Boston Globe shows KFC how to do this, son:
Americans have long mastered double-, triple-, and quadruple-decker sandwiches. And yet this ostensibly innovative new sandwich features just one story -- a design that is outdated and ill-suited to sate the average American gullet. And it contains merely two types of meat. Would it have killed KFC to add ground beef? Some pork? And, to wash the whole thing down a bit, a bucket of nacho cheese for dipping? If there's one thing Americans are qualified to do, it's judge fast-food sandwiches, and they are likely to punish KFC for not going nearly far enough. The Double Down is just a 540-calorie disappointment.
Props to The Wire.
