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 walked towards the image, only to find a little old Jewish man sitting at a card table with a bunch of neck tie laid out on it.
The Arab asked, "I'm dying of thirst, can I have some water?"
The Jew replied, "I don't have any water, but why don't you buy a tie?
They are only $100. Here is one that goes well with your robes."
The Arab shouted, "I don't want an overpriced tie, you idiot, I need water!"
The Jew replied "OK, don't buy my ties. But to show you what a nice guy I am, I'll tell you that over that hill, about four miles is a nice restaurant. They have all the water you need."
The Arab begrudgingly thanked him, then staggered away towards the hill and eventually disappeared.
Four hours later the Arab came crawling back to where the Jewish man was sitting behind his card table.
The Jew said, "I told you, about four miles over that hill. Couldn't you find it?"
The Arab rasped, "I found it all right, but your idiot brother wouldn't let me in without a tie."
