An elderly gent realized he needed to purchase a hearing aid, but he felt unwilling to spend much money.

"How much do they cost?" he asked the salesperson.

"That depends," he said. "They run from $2.00 to $2,000."

"Let's see the $2.00 model," said the miserly man.

The salesperson put the device around his neck. "You just stick this button in your ear and run this little string down to your pocket," he instructed.

"How does it work?" asked the man.

"For $2.00 it doesn't work," the salesperson replied. "But when people see it on you, they'll talk louder!"
