Though food critics found it "slimy," "unhealthy" and "undignified," Americans love the Double Down, digesting millions of the notoriously breadless chicken sandwiches in the five weeks since its launch. Calling it an "unprecedented" success, KFC has decided to extend the "limited release" item into the summer. The Double Down certainly isn't helping the nation's obesity problem, but it is finding a place in their (increasingly imperiled) hearts. A look at the numbers behind this "meaty monstrosity":

10 million 
Number of KFC Double Downs sold in the U.S. since its nationwide launch, on April 12

53 million
Number of McDonalds Big Macs sold in the U.S. during the same period (based on annual sales figures of 550 million a year)

Average number of Double Downs sold at each of the 5,200 KFC outlets in America
