Fast-food chain Burger King has created "Whopper Sacrifice," a Facebook app that will give you a coupon for a free hamburger if you delete 10 people from your friends list.
"Now is the time to put your fair-weather Web friendships to the test," the Whopper Sacrifice site explains. "Install Whopper Sacrifice on your Facebook profile, and we'll reward you with a free flame-broiled Whopper when you sacrifice ten of your friends."
The funniest part: The "sacrifices" show up in your activity feed. So it'll say, for example, "Caroline sacrificed Josh Lowensohn for a free Whopper." Unfortunately, you can't delete your whole friends list and eat free (however unhealthily) for a week. The promotion is limited to one coupon per Facebook account.
