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 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.

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 tits," says the man. "Where do you want these blinds?"
