A fleeing Taliban, desperate for water, was plodding through the Afghanistan desert when he saw something far off in the distance. Hoping to find water, he staggered toward the object only to find a little old Jewish man sitting at a card-table with a collection of neckties laid out on it.

The Arab asked, "My thirst is killing me. Do you have water?"

The Jewish man replied, "I have no water. Would you like to buy a tie?  They are only $150. This one goes very nicely with your robes."

"DAMN IDIOT!" shouted the Arab, “I do not need an overpriced tie. I need WATER!”

"OK," said the old Jewish man, "it does not matter that you do not want to buy a tie, and that you insult me. I will show you that you have not offended me.  If you walk over that hill to the east for about four miles, you will find a lovely restaurant. Go! Walk that way! The restaurant has all the water you need!"

The Arab staggered away toward the hill and eventually disappeared. Six hours later he comes crawling back to where the Jewish man was sitting at his table.

The old man said, "I told you, about four miles over that hill. Could you not find it?"

"I found it all right," rasped the Arab. "Your brother won't let me in without a tie!"
