Two men, a Jew and a Gentile, were marooned on a desert island. The Gentile immediately got to work, dragging rocks to spell out “SOS” in huge letters on the beach, gathering driftwood to build a bonfire, and thinking about ways to build a boat.

The Jew, however, merely sat on the beach and waited.

“What’s the matter with you?” the Gentile exclaimed. “Don’t you want to be rescued?”

The Jew said calmly, “Look, I live in a city with a big Jewish Federation. Last year, I donated a million dollars to them. The year before, I donated a million dollars to them. This year, wherever I am, they’ll find me!”
