A man is talking to the family doctor. "Doc, I think my wife's going
deaf."
The doctor answers, "Well, here's something you can try on her to test
her hearing. Stand some distance away from her and ask her a question.
If she doesn't answer, move a little closer and ask again. Keep
repeating this until she answers. Then you'll be able to tell just how
hard of hearing she really is."
The man goes home and tries it out. He walks in the door and says,
"Honey, what's for dinner?" He doesn't hear an answer, so he moves
closer to her. "Honey, what's for dinner?" Still no answer. He repeats
this several times, until he's standing just a few feet away from her.
Finally, she answers, "For the eleventh time, I said we're having
MEATLOAF!"
