In case you thought KFC's Double Down didn't have enough calories, here comes Burger King's NY Pizza Burger.

Composed of four Whoppers topped with pepperoni, mozzarella and marinara sauce on a massive 9.5-inch sesame seed bun, this culinary Frankenstein is cut into six pizza-style slices. A mere serving (one slice) has 420 calories and 24 grams of fat. Wolf down the whole monstrosity and you'll be consuming 2,520 calories and 144 grams of fat or, in terms we mortals can understand, the equivalent of 36 strips of bacon.

If that's not enough to put you off, perhaps this is: The NY Pizza Burger doesn't debut until December and only in midtown Manhattan, according to the New York Daily News.
