Two young nuns were fresh out of the convent when they've been assigned to a rectory that is being remodeled.
"Your first assignment is to repaint the offices. But it's very important that you don't get any paint on your brand new habit." The nuns discuss it and decide that maybe they should just lock the door and paint in the nude, to ensure that they keep their habits paint-free.
They were almost done painting when there was a knock on the door. One panics, thinking she needs to get dressed quickly, while the other one calls out "Who is it?"
"Blind man," replies a voice from the other side of the door. The two nuns look at each other, shrug, and, deciding that no harm can come from letting a blind man into the room, they open the door.
"Nice tits," says the man. "Now, where do you want these blinds?"
