One day, while going to the shop, I passed by a retirement village.

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.

On my return trip, I passed the same retirement village with the same six old ladies lying naked on the lawn.

This time my curiosity got the better of me so I stopped and went inside to talk to the retirement village administrator.

I asked her, "Did you know there are six ladies lying naked on your lawn?"

"Yes," she said, "aren't they darlings?

They're retired prostitutes, and they're having a yard sale ."
