The Naked Nuns

On a really hot day, four nuns were assigned to paint a room in their church..
After sweating for a few hours in those black robes, they decided
to take off all their clothes and paint naked. An hour later,
someone knocked on the door of the church.

"Who is it?" they called out.
"I'm the blind man," came the reply.
The nuns decided to let him in since he wouldn't be able to see them.
They opened the door and led him to the room they were painting.
They were surprised when he walked around the room with no difficulty.
"Okay, sisters," he said, "where do you want the blinds?"
