An old man decided his old wife was getting hard of hearing. So he called her doctor to make an appointment to have her hearing checked. The doctor said he could see her in two weeks, and meanwhile there’s a simple, informal test the husband could do to give the doctor some idea of the dimensions of the problem.
“Here’s what you do. Start about 40 feet away from her, and speak in a normal conversational tone and see if she hears you. If not, go to 30 feet, then 20 feet, and so on until you get a response.”
So that evening she’s in the kitchen cooking dinner, and he’s in the living room, and he says to himself, “I’m about 40 feet away, let’s see what happens.”
“Honey, what’s for supper?” No response.
So he moves to the other end of the room, about 30 feet away. “Honey, what’s for supper?” No response.
So he moves into the dining room, about 20 feet away. “Honey, what’s for supper?” No response.
On to the kitchen door, only 10 feet away. “Honey, what’s for supper?”. No response.
So he walks right up behind her. “Honey, what’s for supper?”
“For the fifth time, CHICKEN!”
