A couple who'd been married for over fifty years were sitting on the sofa, watching television, as they did every night of the week. The wife put down her knitting and said, "Dear, do you remember how you used to sit close to me?" "Yes, I do" he said as he slid over to her side. "Dear," she continued, "do you remember how you used to hold me tight?" "Yes, I do," he said as he reached over and held her. "And," she went on, "do you remember how you used to hug me and kiss me and nibble on my ear?" Suddenly her husband got up and started to walk out of the room. "Where are you going?" she asked. "To get my teeth," he replied.
