Two Naval aviators boarded a flight from Washington to New York. One sat in the window seat, the other in the middle seat.
Just before take-off an Army helicopter pilot got on and took the aisle seat next to the Navy guys.
He kicked off his shoes, wiggled his toes and was just settling in when the Navy pilot in the window seat said, “I think I’ll go up and get a Coke.”
“No problem,” said the Army guy, “Stay there, I’ll get it for you.” While he was gone, the Navy pilot picked up the Army pilot’s shoe and spat in it.
When the Army guy returned with the Coke, the other Navy pilot said, “That looks good. I think I’ll have one too.”
Again, the Army helicopter pilot obligingly went to fetch it, and while he was gone the Navy pilot picked up the other shoe and spat in it too.
The Army guy returned with the coke, and they all sat back and enjoyed the short flight to New York.
As the plane was landing the Army pilot slipped his feet into his shoes and knew immediately what had happened.
“How long must this shit go on?” he asked. “This enmity between the Navy and the Army … this hatred … this animosity … this spitting in shoes and pissing in cokes?”
