A wife arrived home from a shopping trip, and was horrified to find her husband in bed naked, with a lovely young thing. Just as she was about to storm out of the house, her husband stopped her and said, "Honey, before you leave, please let me explain." The wife stopped to listen. He continued, "I was driving along the highway, and I saw this young girl looking very tired and bedraggled, so I offered her a lift. She was also hungry, so I brought her home and made her a meal from the roast beef in the refrigerator which you didn't like. She was wearing some very worn sandals, so I gave her a pair of your shoes which you'd discarded simply because they were out of style. She was cold, so I gave her the sweater I bought you for your birthday - the one you never wore because the colors didn't suit you. Her slacks were torn, so I gave her a pair of yours that were perfectly good, but much too small for you now." The wife seemed to have no problem with any of this, but still needed just one question to be answered. "That's all fine and good," she said, "but why did I find you both in our bed with no clothes on?" The husband replied, "Well, that's simple... see, as she was about to leave the house, she turned to me and asked, "Is there anything else that your wife doesn't use anymore?"
