|A man realized he needed to purchase a hearing aid, but he felt unwilling to spend much money.|
"How much do they cost?" he asked the clerk.
"That depends," said the salesman. "They run from $2 to $2,000."
"Let's see the $2 model," he said.
The clerk put the device around the man's neck, "You just stick this piece of plastic in your ear and run this little string down into your pocket," he instructed.
"How does it work?" the customer asked.
"For $2, it doesn't work," the salesman replied. "But when people see it on you, they'll talk louder."
