The Arab asked, "Do you have water?"
The Jewish man replied, "I have no water. Would you like to buy a tie? They are only $5."
The Arab shouted, "Idiot Jew! Israel should not exist! I do not need an overpriced tie. I need water! I should kill you, but I must find water first."
"OK," said the old Jew, "it does not matter that you do not want to buy a tie and that you hate me. I will show you that I am bigger than that. If you continue over that hill to the east for about two miles, you will find a lovely restaurant. It has all the water you need. Shalom."
Muttering, the Arab staggered away over the hill.
Several hours later he staggered back, near collapse. "Your brother won't let me in without a tie."
