Blind man

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.

"Nice boobs," says the man, "Where do you want these blinds?"
