Easy Listening

It seems an older gentleman had serious hearing problems for a number of years. He went to the doctor and the doctor was able to have him fitted for a set of hearing aids that allowed the gentleman to hear 100%.
A month later he returned to the to the doctor and the doctor said, "Your hearing is perfect. Your family must be really pleased that you can hear again."
"Oh, I haven't told my family yet." the gentleman said. "I just sit around and listen to the conversations. I've changed my will three times!"
