See no evil
One day two nuns were inside the church painting when the air conditioner went out. It was one of the hottest days of the year and soon the heat was more than they could stand. They had to be finished that day so one of the nuns suggested taking off their heavy garments since they were the only ones there. The other nun said "I don't have anything on under mine." "I don't either" replied the first nun "but who is going to see us?" They got undressed and began painting again. They were much more comfortable and doing quite well when suddenly there was a knock at the door. They froze. "Who is it?" asked the first nun. "It is the blind man from down the street" a man answered from behind the door. They talked it over and, seeing no harm since the man was blind, opened the door. A man walked in with his arms full of boxes. He took one look at the nuns and with a puzzled look asked "Where would you like these blinds?"
