This UK TV ad for the Department for Transport's anti drink-drive campaign, THINK!, might need to come with a health warning. The ad purports to be a hidden camera stunt where men walk into a public toilet and are confronted with a body smashing through the mirror, as if through a car windshield, as they wash their hands. In fact, the men were played by actors, but the spot, by Leo Burnett London, is sure to shock viewers. Its message is to "think what impact a drink could have on your night out".
