An elderly lady of 85 went to live in the nursing home. All of her life she had never been married, and never had sex. In fact, she had never even seen a penis, not even once.
After awhile she met a gentleman in the nursing home who took an interest in her. After awhile the topic turned to sex, and she told the gentleman about her situation. And he told her, "thats okay, I can't get it up anymore, but you can hold it for me, won't you. Just you."
So each time they got together she would hold his penis, but not do much else.
One day she goes to his room to see him and he isn't there. So she goes to the activity room, and he isn't there either. So she starts looking for him all over the place, and finally finds him in a corner with another woman.
She goes up to the guy and says, "hey, what's going on here. I thought I was going to be the only one around here that gets to hold your penis. And he says, well, you used to be, but now I have found this lady. And so the first lady says, well, what does she have that I haven't got. And he says "parkinsons"
