An elderly gentleman had been deaf for years.
He went to the doctor and he was able to have a set of very discreet hearing aids fitted.
He went back a month later for a check up.
The doctor said,"Your hearing is perfect. Your family must be really pleased now that you can hear again."
The gentleman replied,"Oh, I haven't told them yet. I just sit around and listen to their conversations. I've changed my will three times already."
