American food outlet Denny's has offered to team up with Burger King for World Peace Day after the burger giant was spectacularly rejected by notorious rivals McDonalds.

The original proposal was to create a 'McWhopper' in a joining-together of two of the world's most iconic burger brands.

The proposal acknowledged the perceived competition between the two fast-food joints, and suggested that the two fast food giants could put aside their differences to celebrate World Peace Day.

Burger King suggested a "neutral area" in which to set-up a pop-up shop selling the 'McWhopper' burgers, which would be paid for by customers writing on the trays who they would make peace with on World Peace Day.

The CEO of McDonald's responded on their official Facebook page, shooting down the idea and suggesting that Burger King "join us in a meaningful global effort".

They continued: "Let's acknowledge that between us there is simply a friendly business competition and certainly not the unequaled circumstances of the real pain and suffering of war", adding "a simple phone call will do next time".

However, breakfast joint Denny's has now jumped into the fold, offering Burger King the chance to make a collaboration burger with them.

"Hey Burger King, how about a Slammper, or a Whampper or a Whoppasslamus-rex or something?", the Denny's account tweeted.
