A man thought his wife was going deaf, but didn't know how to broach the subject to his her so he called the family dr for advice.
The Dr said " there is a simple test to see how bad her hearing is. Stand 40 feet away from her and ask her question. If she doesn't reply, move to say 30 feet away and ask the same question. If she still doesn't reply, keep moving closer, asking her the same question until she answers you".
That night the husband stands about 40 feet away and says to his wife in a normal voice " honey. What's for dinner". No response.
He moves to stand 30 feet away and says " honey. What's for dinner". Again no response.
He keep moving forward 10 feet at time until he is right behind his wife. "What are we having for dinner" he asks.
"Dammit Fred. For the 5th time, we're having chicken".
