Quote from Pabst:
An Arab and a Jew are on seated next to each other on a long flight from New York to L.A. Preferring comfort the Jewish gentleman removes his shoes while airborne. Mid flight, in socks, he needs to retire to the washroom for some brief relief. As the Jew is getting up the Arab asks" I cannot drink liquor but a soft drink would sooth my thirst, when you return could you bring me a drink?"
"Of course" replied the Jew. As soon as the Jew leaves his seat the Arab leans down and spits in each of the Jew's shoes. The Jew returns. A while later, the shoeless Jew once again excuses himself from his seat, once again the Arab spits in the Jews shoes. With his usual decorum the Jew returns holding a drink for the Arab. As the plane approaches LAX the Jew places his feet in the moist, gooey shoes. "Oh" the Jew moans, "When will it end. The suffering, the mistrust, the spitting in the shoes, the pissing in the drinks...."
