Two nuns are ordered to paint a room in the convent, 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 and shrug, and deciding that no harm can come from letting a blind man into the room, they open the door.
says the man, 'where do you want these blinds?'
