Supposedly This Story is True...
Deciding to do some back-yard landscaping, my father-in-law went to the brickyard to buy a quantity of bricks. When he asked the salesclerk about the cost, the man replied, "The more you buy, the cheaper they are."
"Is that so," said my father-in-law. "Then just keep loading them on my truck until they're free."
Question: Why would one expect that this father-in-law has not had calculus (or studied limits)?
