In the year 2000, a Belgian man went to his local priest and confessed: "Forgive me, Father, for I have sinned. During the Second World War, I hid a Jewish man in my attic."
"That's not a sin," said the priest. "It was an act of great kindness."
"But I made him agree to pay thirty-five francs for every week he stayed."
"I admit that wasn't particularly charitable," said the priest, "but you did it for a good cause."
"Thank you, Father," said the man. "That is a great relief to me. I have just one more question."
"What's that?"
"Do I have to tell him the war is over?"
