Will the Mc Whopper really happen?

BK proposed Mc Donald to work together just for 1 day this year. They are proposing to make a special burger “The Mc Whopper” which will be available for only one day(World Peace day). The question remains. What will Mc Donalds do with this proposal. It looks like the Kings have put Ronald in a tight corner. This one time offer is too good to turn down.
