Hearing Check...

Having lost most of his hearing a number of years ago, this elderly man goes to the doctor to be fitted with hearing aids which promise to allow him to hear 100%. A month later, he returns to the doctor for a check up on his progress. The doctor tells him that his hearing is perfect and asks if his family is pleased. The man says, "Oh, I haven't told them about the hearing aids yet. I just sit around and listen to them talk. I've changed my will three times!"
