Three cowboys were driving along a country road, having a few bottles of beer on the way, when they heard a siren.
"Oh, Oh, guys" the driver said. "Be darned if the sherrif isn't behind us! Quick, take the labels off your bottles and stick them on your foreheads, and let me do the talking." His buddies did what he told them, and waited to see what would happen.
The driver pulled over, and the sherrif came walking up to his window.
"Howdy fellas," he said as he leaned in the window. "What you boys up to today? You wouldn't be drinking and driving would you?"
"What makes you think we've been drinking?" asked the driver.
"Well, you do have those labels stuck to your foreheads."
"Gee, officer, we haven't been drinking, and those aren't labels, we're on the patch!"
