A young woman was taking her new city boyfriend home to the family farm.
Keen to appear interested in all things rural he pointed at the first cattle they saw.
“What a cute bunch of cows!” he said.
“Not a bunch, herd”, she replied.
“Heard of what?” he asked.
“Herd of cows,” she said.
“Of course I’ve heard of cows,” he said.
“No, a cow herd,”she explained.
“None of them could have heard us, the windows are up,” he said. Besides, why would I care, I have no secrets to keep from a cow!”
