An old guy was fed up of his wife not answering him when he spoke to her so he decides to try a quick hearing test. He took her into the garden and stood at the end with her back to him. He walk 10 yards back up the garden and then shouts ‘can you hear me’ - no response. He steps a yard closer and shouts ‘can you hear me’, again no response. He continues to do this until he is 1 yard behind and shouts ‘can you hear me’. she turns to him and says ‘for the tenth time yes’.
