A man in Amsterdam felt that he needed to confess, so he went to his priest, "Forgive me Father, for I have sinned. During WWII I hid a refugee in my attic." "Well," answered 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?"
