How far would you go for a free burger?
Fast-food chain Burger King has a whopper of a marketing campaign underway for its Angry Whopper.
BK decided to tap into Facebook to promote the new burger, which is a Whopper with spicy crispy onions, jalapeños, pepper jack cheese, bacon, tomatoes, lettuce, mayonnaise, and spicy "Angry Sauce".
People using Facebook can install the "Whopper Sacrifice" to their profile.
The app offers a coupon for a free Whopper if you delete 10 people from your friends list.
When you get rid of a friend it shows up in your activity feed. So it'll say, you sacrificed that person for a free Whopper.
