The people at Burger King have some interesting ideas lately. Not only do they want you to smell like your food, but they also want you to sacrifice your friends in the name of hamburgers.
If you de-friend 10 people on Facebook via the Whopper Sacrifice application, you get a free Whopper. Unlike normal de-friending, this will also notify your sacrificed friends (now enemies?) so they'll get on board, too.
A little heartless? Sure. But what a great idea. Any company can make a Facebook group or invite you to an event or make an application in which you can send people little hamburger icons. It's a nice change to see something a little more underhanded.
I'm not sure if it would be better to de-friend those people you don't really care about (hey guy from that discussion section four years ago!) or people you're actually friends with, who would get the joke and whom you could re-friend after you get your free lunch.
Eat heartily, hamburger lovers. You may not have friends, but you sure do have five minutes of happiness.
