An elderly gentleman had a serious hearing problem for several years. He went to the doctor, who fitted him with a set of hearing aids that allowed him to hear perfectly again.
The old man returned to the doctor after a month. The doctor said, “Your hearing is now perfect. I’m sure your family must be very happy that you can hear again.”
The old man replied, “Oh no, I haven’t told my family yet. I just sit and listen to their conversations… I’ve already changed my will three times!”
