Talking urinal cake

"Don't drive drunk." That's the message every government, charity and local organization wants to get out during the Fourth of July holiday. It's sound advice, too, even from a potty mouth.

According to The Detroit News, the state of Michigan has bought 400 talking urinal cakes that will remind men that if they've had a few drinks, they shouldn't drive.

"Listen up. That's right, I'm talking to you. Had a few drinks? Maybe a few too many?" the urinal cake says after being activated by a tiny motion sensor in it. "Then do yourself and everyone else a favor: Call a sober friend or a cab. Oh, and don't forget to wash your hands."

The brainchild of the Maryland-based Wizmark, which has broken new ground with its electronic urinal advertising devices, the $21 talking cake is part of a bigger campaign to promote safe holiday driving.
