Lost at Sea?

Yossi and Janine, an elderly Jewish couple, are sitting together on an aeroplane flying to the Far East. Suddenly, 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 in a few minutes time. The good news is that I can see an island below us that should be able to accommodate our landing. The bad news is that 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."Yossi turns to Janine and asks, "Janine, dear, did we turn off the oven?" and Janine replies, "Of course." "Janine, are our life insurance policies paid up?" "Of course." "Janine, did we pay our pledge for the synagogue appeal?" "Oh my God, I forgot to send off the cheque." "Thank Heaven! They'll find us for sure!"
