Husband and wife
He said to the doctor, "I think my wife is deaf because she never hears me the first time and always asks me to repeat things."
"Well," the doctor replied, "go home tonight, stand about 15 feet from her, and say something. If she doesn't reply, move 5 feet closer and say it again. Keep doing this until we get an idea about the severity of her deafness."
The husband went home and did exactly as the doctor had instructed. He started off 15 feet from his wife in the kitchen as she was chopping some vegetables.
He said, "Honey, what's for dinner?"
He heard no response. He moved 5 feet closer and asked again. No reply. He moved 5 feet closer. Still no reply.
He finally got fed up and moved right behind her, about an inch away, and asked again, "Honey, what's for dinner?"
She replied, "For the fourth time, vegetable stew!"
