CHARLESTON, W.Va. -- When do you know you've had enough to drink?
Maybe it's when the urinal cake in the men's room of your favorite watering hole starts commenting on your marksmanship.
That's the premise behind an experimental sober driving initiative taking place in Colorado, following a debut in Michigan last year.
During the Labor Day weekend, the men's rooms in 15 Colorado bars were equipped with motion-activated "interactive urinal communicators," or IUCs, all of them bearing the logo of the Colorado Department of Transportation's "Heat Is On" anti-drunk-driving campaign.
Once contact is made with the IUC, a jaunty male voice similar that of a DJ on a morning drive radio show chimes in with some play-by-play commentary.
"Keep a constant stream on this urinal cake and let's see how drunk you are," the cheery IUC voice says, upon "activation."
While those remarks are bound to cause some startled bar patrons to send misdirected fire to the bathroom floor, the IUC dude proceeds to deliver a critique to those still making contact with the talking cake.
