One day, while going to the store, I passed by a nursing home. On the front lawn were six old 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 old ladies lying naked on the lawn.

This time my curiosity got the best of me, I went inside to talk to the Nursing Home Administrator. "Do you know there are six ladies lying naked on your front lawn?'

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