About a month ago, 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?"
