'Pub Loo Shocker,' British Anti-Drunk Driving PSA, Is So Terrifying It Might Just Save Lives.

A viral British anti-drunk driving campaign video is receiving a lot of attention this week for a sobering strategy that aims to literally scare the crap out of potential offenders.

The #PubLooShocker video, just 52 seconds long, features "unsuspecting" drinkers in a bar bathroom. They are suddenly brought face-to-face, literally, with the bloody head of a person smashing through the mirror (as one might a car windshield).

While the pub patrons are reportedly actors, and the head is obviously fake, the effect of video is deeply disturbing.

Produced by Leo Burnett for England's Department for Transport THINK! campaign, the PSA certainly has people talking. After only a day on YouTube, the video has already racked up hundreds of thousands of views, and it's setting Twitter abuzz.

So far, online commenters seem to be reacting positively to the campaign.
