Two Nuns are ordered to paint a room in the convent, and the last
 instruction from Mother Superior is that they must not get even
 one 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 the
 room in the nude.
 
 In the middle of the project, there comes a knock on the door.
 "Who is there," calls out one of the Nuns. "
 "The blind man," replies a voice from the other side of the door.
 
 The two Nuns look at each other and shrug, deciding that no harm
 can come from letting a blind man into the room.  They open the
 door.
 
 "Nice boobs, sisters" remarks the man with a wry smile, "now,
 where do you want these blinds?"
