When Burger King urged McDonald's to collaborate on a beautiful piece of junk food artistry, many fast food fans got their hopes up.
However, despite full-page ads in the New York Times and Chicago Tribune newspapers asking McDonald's to call off the "burger wars", it seems the beef is just too big.
The ads, paid for by Burger King, appealed to McDonald's to join forces with them and sell a one-day only McWhopper burger for charity at a special pop-up location halfway between the two companies' headquarters.
The proceeds of the collaboration were to go to the nonprofit organisation Peace One Day, the New York Times reported.
