A young city boy visiting a dude ranch wanted to be appear 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, isn't that fine-looking bunch of cows over there."
The hired hand replied, "Not 'bunch,' it's 'herd.'"
"Herd of cows."
"Sure, I've heard of cows!" finished the city boy excitedly, "there's a big bunch of 'em right over there."
