How far would you go to get a free hamburger? Well, if you wanted a free Whopper from Burger King, you’d have to unfriend 10 friends on Facebook and let them know that you “sold” their friendship for a free whopper!
It may sound weird but it was all part of a marketing campaign called “Whopper Sacrifice”:
In early 2009, Burger King launched a campaign according to which, if you unfriended 10 friends on Facebook, you were entitled to a free Whopper. But there was a catch: by using the Whopper Sacrifice application, your friends would not only get notified that you unfriended them, they would also receive a message telling them that their friendship was less valuable than a Whopper!
Would you do it?
