An elderly couple decides, “Tonight is the night.” She slips into something sexy and crawls into bed. He heads into the bathroom. She waits and waits until she can’t stand the suspense; she climbs out of bed, gets up, goes to the bathroom, and opens the door. She sees him bent over, trying to put on a condom. She giggles, “Honey, what are you doing? I’m 86 years old. There’s no way I can get pregnant!” He looks up at her and says, “I know, honey, but you know how dampness affects my arthritis!”
