Two nuns are ordered to paint a room in the convent, and the last instruction of the Mother Superior was 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 was a knock at the door. "Who is it?" called one of the nuns.

"Blind man," replied 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, so they open the door.

"Nice boobs," said the man. "Where do you want these venetian blinds to be hung?"
