Why can't we just get along?

[THEFERMANATOR]

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, a Marine sat down in the aisle seat.
After takeoff, the Marine 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 the Marine, "I'm in the aisle seat,
"I'll get it for you."
As soon as he left, one of the Arabs picked up the Marines shoe and spat in it.
When the Marine returned with the coke, the other Arab said
"That looks good, I'd really like one, too"
Again, the Marine obligingly went to fetch it.
While he was gone the other Arab picked up the Marines other shoe and spat in it.
When the Marine returned, they all sat back and enjoyed the
flight.
As the plane was landing, the Marine 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?
The pissing in cokes?..."
