New Hearing Aids
An elderly gentleman had serious hearing problems for a number of years.
He finally went to a doctor, and was fitted with excellent new hearing aids.
He returned a month later for a checkup, and the doctor said, “Your hearing is perfect! Your family must be really pleased that you can hear again.”
The gentleman replied, “Oh, I haven't told my family just yet. I still sit around quietly; but, now I listen to the conversations. I've changed my will three times already.
