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, and 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, and they're
having a yard sale."
