'McWhopper' Mega-Burger Would Have Mega-Calories

Burger King is proposing a one-day truce with its fast-food competitor McDonald's to create the "McWhopper," a combination of the Big Mac and the Whopper, the most popular burgers at the respective chains. Neither restaurant has released information about the exact nutritional value of the hypothetical mega-burger, which Burger King wants to sell in honor of World Peace Day in September. According to the Burger King proposal, the McWhopper would be 6 parts Big Mac and 6 parts Whopper.
