Here is a rather off the wall guerilla marketing campaign. This campaign against drunk driving was done in Germany and is definitely one of the coolest anti-drunk driving campaigns. A pressure sensitive gadget was placed inside urinals. Above the urinals was a television screen with a video game.
As you handle your business at the urinal, the video game starts. It is a racing game and eventually you lose control and crash. Having these video game components in bathrooms at various bars drives home the message that if you drive while drunk you will have an accident. This goes further than urinal cakevertising. The suggestion at the end of this is to call a cab, and a local cab company phone number is displayed on the screen. I think that this promotion really needs no further help, but if it were to go one step further some promotional pre-paid phone cards would make a great addition to this campaign.
