Two nuns are ordered by their Mother Superior to paint a room in the convent, but not to get a drop of paint on their habits. So the nuns decide to lock the door of the room, remove their habits, and paint in the nude.After a while theres a knock at the door. "Who is it?""Blind man," The two nuns look at each other, shrug, and decide what harm can there be  letting a blind man into the room, so they open the door.The man comes in and says "Holy mary mother of god, sisters!  Where do you want me to put these blinds?"
