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 old ladies laying naked on your
front lawn?"

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