Three nuns in church on a hot day decide to remove their robes because of the heat. Not an unusual habit on a hot day. So about a half hour later, the door bell rings while their robes are slumped over pews clear across the huge chapel.
They ask who it is. "The blind man," a voice replies.
The three nuns decide to simply open the door because the man is blind. He walks in, looks at the nuns and says, "Nice tits! Where do you want me to install these blinds?"
