On a hot summer day, two nuns - both young, blonde and beautiful ? are working in the church library putting away books. After working feverishly to get the job done, the first nun turns to the second and says, "I can't take this heat anymore! Do you think it would be all right if we removed our shirts to cool off while we worked?"

The second nun, feeling the heat herself, decides that it would be acceptable since no one else was present. She locked the door and closed the curtains, and then the two nuns removed their shirts and kept working. Suddenly, there's a knock on the door.

"Who is it?" asks the first nun.

"It's the blind man," says the voice behind the door.

"Well, a blind man can't see our nakedness. We can let him in," the other nun says, and opens the door.

"Wow!" says the blind man, "Nice tits! I gotta run back to the truck. Where do you want me to install these blinds?"
