KFC is doubling down on one of its most questionable menu items.

The Double Down, a bacon and cheese monstrosity sandwiched between two fried chicken filets instead of bread, is coming back on April 21, USA Today reported Wednesday morning.

KFC spokesman Rick Maynard told The Huffington Post it would again discontinue the "sandwich" after May 25.

When the 540-calorie fast-food fix first launched four years ago, on April 12, 2010, KFC extended the limited-time offer to meet high demand after it sold more than 10 million Double Downs in the first month.

Many restaurants kept it on menus into 2011, and "a handful" have been offering it as an off-the-menu item for years, he said. But the sandwich hasn't been marketed nationally in four years, Maynard said.

"At this point, we're thinking about this as a limited-time only kind of product," Maynard said. "We'll have to see what America thinks."

KFC is currently planning a national social media campaign focusing on the “Double Down Dare."

Originally discredited as a "stunt food" by critics, the Double Down turned out to be pretty successful internationally, too.

The sandwich was most recently reintroduced in January at KFC's branches in the Philippines.

And while the Double Down may be a nutritionist’s nightmare, it hardly stacks up to some other artery-clogging fast-food offerings.
