A nun is in the shower when there is a loud knock on the door to the convent. All the other nuns are working out in the back garden and cannot hear the knocking.
So, the showering nun calls out, "who is it?"
To which the following reply comes, "I am the blind man from town."
The nun runs down the stairs naked to open the door.
"Great tits", says the man. And then proceeds to say, "So, where do you want these blinds?"
Thought I would share this little piece of Australian humour.
