[My thanks to Hilary A for the following]
Rabbi Levy is waiting in the queue at Bank Leumi when a hippy-looking bearded young man joins the queue just behind him. The man is holding a very full looking leather briefcase. Rabbi Levy immediately notices that one of the fasteners on the man’s briefcase is undone and the other fastener looks like it’s going to burst open, so he says to the man, “You’re going to lose the contents of your briefcase.”
Just then, the briefcase bursts open and spills its contents onto the floor. The man stares at Rabbi Levy with fear in his eyes and replies, “How on earth did you do that?”
