BK Rewards Facebook Users for Ending Friendships

Burger King is giving away a coupon for a free Whopper if you cut 10 of your Facebook friends loose. The Whopper Sacrifice is a new Facebook application that lets your ex-friend know you've ended the friendship because your love for the Whopper is stronger.

Crispin Porter + Bogusky created the Facebook application and Whopper promotion. The agency is also responsible for the BK Polarizer application, which gauged Facebook users against their friends on political views during the election season.
