Two nuns were 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 decided to lock the door of the room, strip off their habits, and paint in the nude. In the middle of the project, there came 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 looked at each other and shrugged. The decided that no harm could come from letting a blind man into the room and opened the door.
“Nice tits,” said the man, “where do you want these blinds?”
