During WWII, I hid a refugee in my attic.""Well," answers the priest, "that's not a sin."'"But I made him agree to pay me 20 guilders for every week he stayed.""I admit that wasn't good, but you did it for a good cause.""Oh, thank you, Father. That eases my mind. I have one more question.""What is that, my son?""Do I have to tell him the war is over?"
