Two elderly residents, a man and a woman, were alone in the lounge of their nursing home one evening. The old man looked over and said to the old lady, "I know just what you're wanting. For £5 I'll have sex with you right over there in that rocking chair." The old lady looked surprised but didn't say a word. The old man continued, "For £10 I'll do it with you on that nice soft sofa over there, but for £20 I'll take you back to my room, light some candles, and give you the most romantic evening you've ever had in your life." The old lady still says nothing but after a couple of minutes, starts digging down in her purse. She pulls out a wrinkled £20 bill and holds it up. "So you want the nice romantic evening in my room," says the old man "Get serious," she replies. "Four times in the rocking chair."
