Mobilia Shopping Mall : Easier Parking

To promote free underground parking at a Swedish shopping mall, Halva Kungariket placed one car on top of another -- and left it there for the media and the public to jump on. Of course, blogs and social media picked it up, which was when the real message of the campaign was tacked onto the cars.

The real fun -- and creativity -- came when the cars were the victim's of some needless hooliganism.
