The head nun tells the two new nuns that they have to paint their room without getting any paint on their clothes.
So the one nun says to the other, “Hey, let’s take all our clothes off, fold them up, and lock the door.” So they do this, and begin painting their room.
Soon they hear a knock at the door. She asks who is it?
The voice behind the door replies, “It’s the blind man.”
The nuns look at each other, shrug, and decide it’s safe. One of them opens the door.
The man walks in and says, “Nice room! Where do you want me to hang these blinds?”
