One day, while going to the store, I passed by a nursing home. On the front lawn were six elderly
ladies lying naked on the grass. I thought this was a bit unusual, but continued on my way to the store.

On my return trip, I passed the same nursing home with the same six elderly ladies lying naked on the lawn.

At this point, my curiosity got the best of me, so I went inside to talk to the nursing home administrator.

"Do you know there are six elderly ladies lying naked on your front lawn?"

"Yes," she said. "They're retired prostitutes and they're having a yard sale."
