A Jewish couple, are sitting together on an airplane flying to the 
Far East. Over the public address system, the Captain announces: 
"Ladies and Gentlemen, I am afraid I have some very bad news. Our
engines have ceased functioning, and this plane will be going down 
momentarily. Luckily, I see an island below us that should be able to 
accommodate our landing. This island appears to be uncharted; I am
unable to find  it on our maps. So the odds are that we will never be
rescued and will have to live on the island for a very long time, if not
for the rest of our lives. A few minutes later the plane lands safely on
the island, whereupon Morris turns to his wife and asks, "Esther, did
we pay our pledge to the Yeshiva yet?" No Morris!" she responded.
Morris smiles, then asks, "Esther, did we pay our UJA pledge?" 
"Oy no, I forgot to send the check!!" Now Morris laughs. 
"One last thing, Esther. Did you remember to send our Temple
Building Fund check this month?" "Oy Morris I forgot that one too!" 
Now Morris is practically choking with laughter. Esther asks Morris,
"So what are you smiling and laughing about?

Morris responds, "They'll find us."
