A young man visiting a dude ranch wanted to look macho, so he went out walking with one of the hired hands. As they were walking through the barnyard, the visitor tried to begin 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."
