I can’t hear you
An elderly gentleman with serious hearing problems goes to the doctor who fits him with hearing aids that allow him to hear at 100% for the first time in many years.
The elderly man goes back in a month for a checkup. The doctor says, “Your hearing is perfect. Your family must be really pleased that you can hear again.”
To which the gentleman replies, “Oh, I haven’t told my family yet. I just sit around and listen to the conversations. I’ve changed my will three times!”.
