Whopper sacrifice

Kev Chesters says:

New campaign running in the States whereby you get a free Whopper in exchange for deleting ten friends from Facebook. (The site is 'whopper sacrifice'.)

The theory being that you might like your mates but you love the burger.

Normally when
deleting friends you get no notification; but this application, once
installed on FB, will send the deleted friend a note to tell them they
have been sacrificed in exchange for a burger.

Genius. I'm presuming it is Crispin.

Only works in the US
at the mo. So far nearly 55,000 friends have been sacrificed. I think it only
launched this week so that’s not bad.

Is this a great idea? Or have I gone bonkers?
