There was an old man in a very nice nursing home with a pool. Everyday all the people there were allowed to sit outside and bask in the sunlight. While the old man was laying back on his chair, he kept noticing a nice older woman that kept making eye contact so after a few days of it he decided to ask something of her.

"Hey, we've been seeing eachother, and I was wondering, would you want to sit next to me and hold my dick?"

Surprisingly enough she obliged and it became their new routine. Things went well for them for the next couple of weeks, until one day the woman came out to see him sitting with a different old woman holding his dick. Infuriated she confronted him, "WHY IS THIS WOMAN HOLDING YOUR DICK?! WHAT DOES SHE HAVE THAT I DONT??"

"Parkinsons"
