joke: that explains a lot A farmer has to go to town. Unfortunately, he's expecting the artificial insemination
....guy a little later that day.
So he takes his not-too-bright wife to the barn and says, "See this nail? That means this is the right stall. This is the cow that we need inseminated." And the farmer goes off to town.
When the artificial insemination guy shows up, the farmer's wife dutifully leads him to the barn. She says, "Well, here's the nail, so this is the cow."
The artificial insemination guy says, "What's the nail for?"
And the farmer's wife says, "I guess that's where you hang your pants."
