The Blind Man

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 look 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 ? "
