Michigan is trying a novel technique for cutting down on drunk driving: filling bathrooms with responsible talking urinal cakes, formally known as Interactive Urinal Communicators.

Then do yourself and everyone else a favor: Call a sober friend or a cab. Oh, and don't forget to wash your hands." Some will also sing and light up.
Four hundred of the devices will be sent to 200 restaurants and bars ahead of July 4, so they'll be in place for Independence Day celebrations, the Detroit News reports. The Office of Highway Safety Planning notes that the bathroom is often the last place men stop before leaving the bar.
