Burger King wants McDonald’s to join forces in creating the McWhopper for world peace

The fast food chain proposed to set aside differences and create the McWhopper – a hybrid of each company's signature burgers, the Big Mac and the Whopper.

Fastfood giant Burger King has asked rival company McDonald’s join with it and create one burger to rule them all for International Day of Peace.

Calling for a one day burger-war ceasefire, the fast food chain proposed to set aside differences and create the McWhopper – a hybrid of each company's signature burgers, the Big Mac and the Whopper.

The fast food giant has also set up a website to make its proposal, even suggesting a recipe for the new hybrid burger: it will contain six ingredients from the Big Mac (cheese and special sauce) and six from the Whopper (the flame-grilled patty and onions).

Burger King says the McWhopper would be sold for one day at a pop-up store in Atlanta, Georgia – a meeting point between both company’s headquarters - and sales would benefit Peace One Day, a non-profit organization campaigning to make Peace Day Sept. 21.

“Let’s make history and generate a lot of noise around Peace Day. If they say no, we’ll hopefully have, at the very least, raised much-needed financial support and consciousness for the great cause that is Peace One Day,” Fernando Machado, senior vice president for global brand management at Burger King, said in a statement.

McDonald’s however seemed to shy away from the McWhopper collaboration in a Facebook post. McDonald’s CEO Steve Easterbrook said: “Dear Burger King. Inspiration for a good cause… great idea, We love the intention but think our two brands could do something bigger to make a difference.”

McDonald’s is yet to officially decline the offer.
