With the holiday season here, agencies Ruby, Red Brick Road and unit9 have launched Know the Signs, a site that puts a new twist on Heineken's "Enjoy Responsibly" campaign.

The site asks visitors to watch surveillance footage of a boisterous bar scene and spot those who are showing signs of impending or visible drunkenness. Visitors can use a virtual remote to pan and click on specific areas of the bar to spot the embarrassing characters including a fighter and an exhibitionist. Once you find one, a humorous video plays to show how their night ends up after too much boozing. After the video, you can send to friends with personalized messages via web or mobile and download a widget for your Facebook or MySpace page.
