One day while walking to the store I passed by a nursing home. On the front lawn were 6 old ladies laying 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 6 old ladies laying naked on the lawn.
This time my curiosity got the best of me and I went inside to talk to the manager.
"Do you know there are 6 ladies laying naked on your front lawn?"
"Yes," he said. "They are retired prostitutes and they are having a yard sale."
