A old man told his doctor, "I don't think my wife's hearing is as good as it used to be. What should I do?"

The doctor replied, "Try this test first. When your wife is at the sink doing dishes, stand fifteen feet behind her and ask her a question. If she doesn't respond, keep moving closer, asking the question until she hears you."

He went home and saw his wife preparing dinner. Standing fifteen feet behind her he said, "What's for dinner, honey?"

Hearing no reply, he moved up to ten feet behind her and repeated the question.

Still no reply, so he moved to five feet.

Finally he stood directly behind her and said, "Honey, what's for dinner tonight?"

She turned around and yelled in his face, "For the fourth time, I SAID CHICKEN, you deaf old fart!"
