At the Ranch

A young man visiting a dude ranch wanted to be “macho,” so he went out walking with one of the hired hands. As they were walking through the barnyard, the visitor tried starting a conversation: “Say, look at that big bunch of cows.”
The hired hand replied, “Not ‘bunch,’ but ‘herd.'”
“Heard what?”
“Herd of cows.”
“Sure, I’ve heard of cows. There’s a big bunch of ’em right over there.”
