An old man and an old woman used to sit in the nursing home all day watching television together.
The old woman would sit there holding the old man's member. The nursing staff tried to get them to stop it but couldn't and decided to leave them alone. Since they weren't hurting anyone, they just put a sheet over the couples lap and kind of ignored it.
But one day the old man didn't show up and when the old woman saw him in the dining hall later that evening she asked, "Where were you today?"
"I watched TV with Martha today" he said quite matter of factly.
With slight cynicism in her voice, the old woman said, "What's she got that I don't have."
The old man paused and said, "Parkinsons."
