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. They ask, "Who is it?"

"Blind man!"

The nuns look at each other, then one nun says, "He's blind, he can't see. What could it hurt." They let him in.

The blind man walks in and says, "Hey, nice tits. Where do you want me to hang the blinds?"
