There's an old joke about that here in the USA and Canada. Two farmers are driving along in an old pickup truck. They stop at a stop sign on a country road, and they notice that there is a dog lying on the grass nearby, licking its balls.

"I wish I could do that," remarks the one guy to the other.

"Well, get out and give it a try if you want," says the other one, "but don't blame me if he bites you."
