Sometimes, the best way to drive a point home is pure, abject terror. And that's the approach Leo Burnett London used in this ad that shows a rather extreme way to discourage drinking and driving.
Unsuspecting bathroom patrons at a British pub were shocked to see the face of a woman come smashing through the mirror -- complete with blood -- as if she'd just gone through the windshield of a car on the other side of the wall. In reality, it was just a mannequin, and the victims of this PSA were most likely actors, but the effect is no less unsettling. To the point where I'm pretty sure I'd never leave my house again had I experienced this. Mission accomplished. [Creativity Online via Taxi]
