I love this one!
An elderly gentleman had serious hearing problems for a number of years. He went to the doctor and the doctor was able to have him fitted for a set of hearing aids that allowed him to hear 100%. He went back in a month and the doctor said, 'Your hearing is perfect. Your family must be really pleased that you can hear again.'
The gentleman replied, 'Oh, I haven't told my family yet. I just sit around and listen to the conversations. I've changed my will three times!'
When I listen to my friend's talking, I make sure I got the intel!
