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