Is it over yet?

It was about a month ago when a Dutchman in Amsterdam felt that he needed
to confess, so he went to his Priest.
"Forgive me Father, for I have sinned. During WWll, I hid a Jewish man in
my attic."
"Well," answered the Priest, "That's no a sin."
"But I made him pay me 20 gulden for each 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. Father, I have one more
question."
"What is it son."
"Do I have to tell him the war is over?"
