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.
"Whats up with the underwear," says the man, "where do you want these blinds?"
