When it comes to marketing strategies for a diarrhea medicine, there doesn't seem to be very many ways to tactfully approach the issue without being downright gross. However, Yovis Viaggio came up with quite a clever campaign to promote its anti-diarrhea medicine. To simulate the condition of having diarrhea, Yovis Viaggio set up a stunt to trap people in the washroom.

The stunt was set up at an airport washroom, and after a traveller entered to use the facilities, a crew puts up an extra set of doors, trapping the traveller in what seemed like a maze.

Behind one of the newly-added doors was an advertisement promoting Yovis Viaggio, which will help them to avoid getting trapped in a washroom ever again.
