This very old couple were sitting on the porch rocking when suddenly the old woman knocked the old guy out of his chair and off of the porch. He got up and dusted himself off and asked her, "Why did you hit me?" She told him, "It is because your dick is too small!" He sat back down and then suddenly he knocks her out of her chair and off of the porch. She asked him, "Why did you hit me?" He replies, "Because after 55 years you know there's a difference!"
