Larry and Harry drove 500 miles to go fishing. They paid a huge sum to rent a cabin and a similar amount for a boat. After fishing for three days, they caught only one fish between them.
On the way home, while Larry drove, Harry fiddled with a calculator. After an hour, Harry said, "Do you realize that this one fish cost us almost $2,000?"
"Wow!" Larry replied. "It's a good thing we didn't catch any more."
