"I got friends in low places." Garth Brooks sang, but now Burger King wants you do to something about it. The fast-food chain, which has been on a marketing tear of late, has released a new widget on Facebook that asks people to delete 10 friends from their network and get a Whopper coupon for all their hassle, AdWeek reports.

The Whopper Sacrifice application automatically notifies deleted friends via Facebook's newsfeed that their friendship simply doesn't outweigh their affection for greasy burgers.

"We thought there could be some fun there, removing some of these people who are friends, but not necessarily best friends," said Jeff Benjamin, executive interactive creative director at Crispin Porter + Bogusky, which crafted the latest campaign for Burger King. This is the second application Crispin has developed for the chain.
