An old man and old woman are talking in a rec room of a nursing home. They are discussing about everything they miss since they have gotten so old.

The man says, "I miss having sex". The woman replies," I do too. I miss satisfying my man." That gives him an idea. 'How about you just hold my penis in your hand?". She was willing to do so. Everyday for about two weeks they met in the rec room, sat next to each other, and she held his penis in her hand all afternoon. Two days in a row, he failed to show up. On the second day, she went searching and found him on the back patio with another elderly woman sitting next to him, with his penis in her hand. The woman yells at him," You two timing SOB, what does she have that I don't have?". He looked up at her, smiled and said, "Parkinsons"
