ladies of the nite

One day, while going to the store, I passed by a nursing home. On thefront 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 ladieslying naked on the lawn.This time my curiosity got the best of me, & I went inside to talk to theNursing Home Administrator. 'Do you know there are six ladies lyingnaked on your Front lawn?''Yes,' she said. 'They're retired prostitutes, - they're having a yard sale.'
