Two Arabs boarded a flight and ended up sitting beside an American, who kicked off his shoes, wiggled his toes, and settled in. Once the captain had turned off the seatbelt sign, the Arab in the window seat said, "I need to get out so I can get a beer." "Me, too," said the Arab in the middle seat. "Don't get up," said the American. "I'm in the aisle seat; I'll get them for you." As soon as he left, the Arabs quietly spat in the American's shoes. The American returned, gave them their beers, and they all sat back and enjoyed the rest of the flight. But as the plane prepared for landing, the American slipped his feet back into his shoes and immediately knew what had happened. "Why does it have to be like this?" he mused out loud. "How long must this continue? This fighting? This hatred? This animosity? This spitting in shoes. This pissing in beers?"
