At this point, nobody's surprised. It's an uncomplicated idea in the year of 2013 d.t. (doritus tacous): every month, or bi-weekly in some quick food places, a fast food restaurant will release an arm-bracingly intense challenge food, an Inceptiony food inside a food, or a Frankenstenian other food jacked into a new food.
It's Occam's razor, really: will a fast food organization actually release that food monstrosity you made a joke about with your friends months ago? The answer comes back clear as day-old mayonnaise on paper: oh, totally. Five years ago, a Doritos chip flavored like Taco Bell would have sounded like an Onion story. So, here we stand in 2013, a time you might call Double-Down Day Plus 1095 (Has it really been three years since KFC's fried chicken-bunned Double Down?).
Last year had some deep fried winners. 2013 was special, though. It was the year we extrapolated on the night-black burger bun, put Sriracha on everything that moved, and physically dropped tacos from helicopters. Among the trends, these were the fast food anomalies that were the most egregious.
