One day, while going to the shop, I passed by a Retirement Village. On the
front lawn was 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 & I went inside to talk to the
Retirement Village 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 garage sale.’

Did they have up and over doors or swing doors 😉
Swing, I think.
And then one of the ladies got up and streaked through the town.
“What the hell was that?”, said a bystander.
“Don’t know”, said his colleague, “but it sure as hell needed ironing,”
