An older couple were having some difficulties, so the husband booked a cruise to try to save the marriage.  The first day was a disaster. She had left her hearing aid at home, and she couldn't hear a thing. To make matters worse, the cruise line had put them in a cabin with bunk beds instead of a king-size bed. Dejected, the man asked her, "Which one do you want, up or down?" The next thing he knows, she rips his clothes off and he has the best sex of his life.

The next day, however, is a disaster again. She was still without the hearing aid and the shuffleboard tournament was rained out. Dejected again, the man asked, "Which one do you want, up or down?" The next thing he knows, she rips his clothes off again and he has even better sex than the night before.

The third and final day was a complete loss. Nothing went right for the man. They leave the boat and fly back home. When they get back home, it's late and they decide to call it a night. She puts on her nightgown, brushes her teeth and puts her hearing aid back in. He figures, "What the hell, it worked on the cruise, might as well try it again." He asks his wife, "So, which do you want, up or down?" She looks at him as if he's lost his mind and says, "What in the hell are you talking about, you old fool?" He says, "Well, whenever I asked you that on the boat, you gave me the best sex I've ever had." She slaps her forehead, "Up or down?  all that time I thought you were saying 'fuck or drown'!!!!"
