One day, while walking to the store, I passed by a Nursing Home.

On the front lawn were 6 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 6 old ladies lying 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 old ladies lying naked on your
front lawn?"

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