Two Democrats boarded a shuttle flight. One sat in the window seat, the other sat in the middle seat. Just before takeoff, a Republican got on and took the aisle seat next to the Democrats. He kicked off his shoes, wiggled his toes and was settling in when the Democrat in the Window seat said "I think I'll get up and get a coke."

"No problem," said the Republican, "I'll get it for you."

While he was gone, the Democrat picked up the Republican's shoe and spit in it. When the Republican returned with the coke, the other Democrat said, "That looks good, I think I'll have one too!"

Again, the Republican obligingly went to fetch it and while he was gone, the Democrat picked up the other shoe and spit in it. The Republican returned and they all sat back and enjoyed their flight. As the plane was landing, the Republican slipped his feet into his shoes and knew immediately what had happened.

"How long must this go on?" the Republican asked. "This enmity between our peoples? This hatred? This animosity? This spitting in shoes and peeing in cokes?"
