Remember when KFC's Double Down took over every news station back in 2010? People were intrigued and appalled by the monstrous bacon and cheese sandwich that swapped its buns for two fried chicken filets.

Since then, other frankenfoods have clogged our memories. Taco Bell's Bacon Waffle Taco, Doritos Locos Taco. Domino's cheese-laden Chicken Crust. Jack in the Box's Stacked Grilled Cheeseburgers. However, die-hards can argue that the Double Down was at the frontier of America's trending love for outrageous grease bombs.

Now, it's back. For those who weren't ready for it four years ago or were heartbroken when it was discontinued, the Double Down returns for a limited time to KFC on April 21. The day after 4/20. Of course.
