A lady from the city and her traveling companion were riding the train through Vermont when she noticed some cows.
“What a cute bunch of cows!” she remarked.
“Not a bunch, herd”, her friend replied.
“Heard of what?”
“Herd of cows.” “Of course I’ve heard of cows.”
“No, a cow herd.”
“What do I care what a cow heard. I have no secrets to keep from a cow!”
