An elderly man had serious hearing problems for a number of years. He went to the doctor who was able to have him fitted for a set of hearing aids that allowed the him to hear 100%.
The man went back in a month for a check-up and the doctor said, 'Your hearing is perfect.. Your family must be really pleased?'
The old guys replied, 'Oh, I haven't told my family yet. I just sit around and listen to their conversations. I've changed my will three times!'
