Two Marines boarded a quick shuttle flight out of Dallas, headed for Houston. One sat in the window seat, the other sat in the middle seat. Just before take-off, a Sailor got on and took the aisle seat next to the two Marines.
The Sailor kicked off his shoes, wiggled his toes and was settling in when the Marine in the window seat said, "I think I'll get up and get a coke."
"No problem," said the Sailor, "I'll get it for you."
While he was gone, the Marine picked up the Sailor's shoe and spit in it. When the Sailor returned with the coke, the other Marine said, "That looks good, I think I'll have one too."
Again, the Sailor obligingly went to fetch it and while he was gone, the Marine picked up the other shoe and spit in it. The Sailor returned and they all sat back and enjoyed the short flight to Houston. As the plane was landing, the Sailor slipped his feet into his shoes and knew immediately what had happened.
"How long must this go on?" the Sailor asked. "This fighting between our forces? This hatred? This animosity? This spitting in shoes and pissing in cokes?"
