One morning, before he goes out to the fields, the farmer says to her,
“The artificial insemination man is coming to impregnate one of our cows today. I drove a big nail into the two-by-four over the cow’s stall. You show him where it is.”
The farmer leaves, and a while later, the artificial insemination man arrives.
Stacy takes him down the rows of cows until she sees the nail.
