There is now a fine line between busting to go to the toilet and being busted drunk behind the wheel.
US authorities are trying to discourage drink drivers with target advertising: urinal deodorisers that "talk".
The Detroit News has reported overnight that 400 talking "urinal cakes" or "trough lollies" will be distributed across the state as part of a trial to combat drunks from getting behind the wheel.
Each device has a built-in recorded voice which says: "Listen up. That's right, I'm talking to you. Had a few drinks? Maybe a few too many?
"Then do yourself and everyone else a favour: Call a sober friend or a cab. Oh, and don't forget to wash your hands."
Each disposable unit costs about NZ$25 and lasts about three months before the battery runs out.
They are activated by motion, rather than moisture, says the company that makes them, Wizmark.
Wizmark also makes urinal deodorisers that "sing and flash lights".
The state of Michigan plans to distribute 400 of the devices in 200 restaurants and bars in the lead-up to the July 4 holiday period.
