Edna and Bill were two residents of a nursing home who had been carrying on a love affair. They were both 96 years old and wheelchair bound. 

Every night, they would meet in the TV room. Edna would passively hold Bill's penis, and they would watch TV for an hour or so. It wasn't much, but it was all they had. 

One night Bill didn't show up. He didn't show up for the next two nights either. Edna assumed he was dead, but then she saw him happily wheeling about the grounds. She confronted him and said, "Where were you these past couple of nights?" 

He replied, "If you must know, I was with another woman." 

"Bastard!" she cried. "What were you doing?" 

"We do the exact same thing that you and I do," he replied. 

"Is she prettier or younger than I am?" she asked. 

"Nope, she looks the same, and she is 98 years old." 

"Well then, what does she have that I don't?" Edna asked. 

Bill smiled and said," Parkinson's disease."
