Two nuns are ordered to paint a room at the convent. They are warned however, by Mother Superior, that they are not to get so much as a drop of paint on their habits. They are unsure of how to accomplish this at first, but then decide it's best to just remove them. They begin to paint the room.
Some time later they are startled by a knock at the door. A man's voice calls out "Blind man!". They begin to reach for their habits, but decide what harm can it be if he's blind? They walk over and open the door.
There is a man standing there with boxes in his arms, who takes one look at them and says, "Nice tits ladies, but where do you want these blinds?"
Good one
