An old man in a retirement home takes a fancy to a woman who had recently begun living there.
One day he gets up the courage to go and talk to her. They soon become friends and after a while he says he would like to make love to her. She agrees and says that when everybody else goes on a day trip they both stay behind at the home and get down to it.
The following week, while the others were out of the home, the old man calls on his new lover. Before getting started, he asks her how she likes to be made love to. She tells him that she loves a man to go down on her. He agrees and goes for it.
After about 30 seconds, he comes back up and says that he is sorry but it just smells too bad down there. She thinks for a minute and tells him that it must be the arthritis. He looks and her confused and states that surely you can’t get arthritis down there, and even if you could it wouldn’t cause that smell.
She says “No, it’s the arthritis in my shoulder. It’s been six years since I’ve been able to wipe my ass.”
