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 any paint on their habits. After conferring about this for a while, the two nuns decide to lock the door to 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 briefly, then figure that no harm can come from letting a blind man into the room. They open the door and greet the blind man. "Nice tits!" exclaims the man. "Where do you want these blinds?"
