The cattle rancher had married a beautiful blonde. One morning, on his way out to check on the cows the rancher said to his wife, “The insemination man is coming over to impregnate one of our cows today, so I drove a nail into the 2 by 4 just above the cow’s stall in the barn. Please show him the cow when he gets here, OK?”
After she acknowledged that she understood, the rancher left to heard the cattle.
After a while, the artificial insemination man arrived and knocked on the front door.
The blonde took him down to the barn. They walked along the row of cows and when she saw the nail, she told him, “This is the one right here.”
The man, assuming he was dealing with an air head blonde, asked, “So tell me lady, ’cause I’m dying to know; how do you know that this is the right cow to be bred?”
“That’s simple,” she said. “By the nail that’s over its stall,” she explained very confidently.
Laughing rudely at her, the man said, “And what, pray tell, is the nail for?”
Looking back as she walked away she said, “I guess it is to hang your pants on.”
