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, 
they're having a yard sale.'
