Visitor on a Dude 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 to begin a conversation, "Say, look at that big bunch of cows."
The hired hand replied, "Not 'bunch,' but 'herd.'"
"Herd of cows."
"Sure, I've heard of cows... there's a big bunch of 'em right over there."
