Two Arabs 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, Drralph, returning from a conference, sat down in the aisle seat.
After takeoff, Drralph kicked his shoes off, wiggled his toes and 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 Drralph, "I'm in the aisle seat, I'll get it for you."
As soon as he left, one of the Arabs picked up Drralph's shoe and spat in it. When Drralph returned with the coke, the other Arab said, "That looks good, I'd really like one, too." Again, the ever accomidating Drralph obligingly went to fetch it.
While he was gone the other Arab picked up Drralph's other shoe and spat in it. When Drralph returned, they all sat back and enjoyed the flight. As the plane was landing, Drralph 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?"
