A man goes to his doctor and says: "I don't think the hearing of my mother-in-law is as good as it used to be, what should I do?"
The doctor replies: "Try this test to find out for sure. When your mother-in-law is in the kitchen 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."
The man goes home and sees his mother-in-law preparing dinner. He stands fifteen feet behind her and says: "What's for dinner today?" No reponse.
He moves to ten feet behind her and asks again, no response.
Five feet, no answer.
Finally he stands directly behind her and says: "Hey, what's for a supper?"
She says: "For the fourth time, I SAID CHICKEN!"
