Retired

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 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're having a yard
sale."
