A man says to his doctor "I think my wife is going deaf, but I don't want to mention it as it'll be tactless and insensitive. Is there any way I can gauge it, preferably without her knowing?" The doctor replies: "There is, it's quite easy, choose a moment when she has her back to you, say something in a normal voice and if she doesn't answer, move a little nearer and say it again and you'll get an idea about her hearing."

So when he comes home from work, his wife is standing with her back to him in the kitchen. He says "What's for dinner love?" but gets no answer. He moves in a little closer "What's for dinner love?" again, no response, and moves in again "What's for dinner love?" - nothing.

By now he's right behind her, he says again "What's for dinner love?" She turns round and says "For the fourth time - chicken!!"

Cheers, Barry!
