Two Palestinians boarded a flight out of London. One took a window seat and the other sat next to him in the middle seat.. Just before takeoff, a rabbi sat down in the aisle seat. After takeoff the rabbi kicked his shoes off, wiggled his toes and was settling in when the Palestinian in the window seat said, ‘I need to get up and get a coke. ”Don’t get up,’ said the rabbi, ‘I’m in the aisle seat, I’ll get it for you.’ As soon as he left, one of the Palestinians picked up the rabbi’s shoe and spat in it..  When the Rabbi returned with the coke, the other Palestinian said, ‘That looks good I’d really like one, too.’ Again, the rabbi obligingly went to fetch it. While he was gone the other Palestinian picked up the rabbi’s other shoe and spat in it.  When the rabbi returned, they all sat back and enjoyed the flight. As the plane was landing, the rabbi slipped his feet into his shoes and knew immediately what had happened. He leaned over and asked his Palestinian neighbors: ‘Why does it have to be this way?  How long must this go on? This fighting between our nations? This hatred? This animosity? This spitting in shoes and pissing in cokes?’
