Thirteen Rabbis were on their way to Jerusalem when their flight ran into a big thunderstorm. One of the Rabbis immediately called over a stewardess. Wanting to calm her nerves, he said, "Could you please tell the pilot that everything will be all right because there are 13 very religious men aboard this plane."
A few minutes later, the stewardess returned from the cockpit.
She told the Rabbi, "Our pilot said that although he was pleased to learn that we have 13 holy men aboard this flight, he would still rather have just one good engine."
