Zubi – Burger King – Impossible Combo Case

Challenge
Over the years, the Burger King brand has
not shied away from campaigns that
generate buzz, in fact they actively seek
them out. Our challenge was to create a
campaign that generates “Talkabilty”, the
brand action that generate a
disproportionate amount of buzz and
publicity, but also moves the promotional
sales needle.
Insight
What is forbidden is also the most sought
after.
Solution
The Impossible Combo, an unlikely pairing
of Burger King’s famous Whopper with
McDonald’s highly-craved French Fries,
Burger King had successfully trolled
McDonald’s several times already. By
conceding that McDonald’s fries are the
best, BK would have a platform to talk
about the superiority of its flagship burger,
The Whopper.
With the help of Burger King’s AOR, David
and partnering with Rappi, the biggest
food delivery service is Brazil, Burger King
offered The Impossible Combo: A Burger
King Whopper and MCDonald’s French
Fries for a limited time.
Results
On the first day of offering the combo of
Rappi, it sold out in 27 minutes, becoming
the most sold order on Rappi that day and
raiding Whopper sales a record 81%.
