Two nuns are ordered to paint a room in the convent which is being renovated, and the last instruction of the Mother Superior is that they must not get even a drop of paint on their habits.
After conferring about this for a while, the two nuns decide to lock the door of the room, strip off their habits, and paint in the nude.
In the middle of the project, there comes a knock at the door.
"Who is it?" calls one of the nuns.
"Blind man," replies a voice from the other side of the door.
The two nuns look at each other, shrug, and decide that no harm can come from letting a blind man into the room.
They open the door.
"Nice body!," says the man. "Where do you want these blinds?"
