To solve a recruitment crisis, the chief of staff of the US Air Force decided to invite all the local young men and women along to an open day at an Arkansas airfield. As he and his staff were standing near a brand new jet fighter plane, two brothers walked over to them. The chief of staff held out his hand, introduced himself and, addressing the first brother, said: "Tell me, son, what skills can you bring to the Air Force?" The young man replied: "I pilot." "Great!" enthused the chief of staff, turning to his aide. "He's just what we're looking for. Get him in straight away to complete all the paperwork." With that, the aide hustled the first brother away. Then the chief of staff turned to the other brother and asked: "So, what skills do you bring to the Air Force?" "I chop wood," he said. "Sorry, son," said the chief of staff. "We don't need wood choppers in the Air Force. Is there anything else you can do?" "I chop wood!" repeated the young man. "Son, you're not listening to me. We don't need wood choppers in the Air Force, not in the twenty-first century." "But you hired my brother," protested the young man. "Of course we did. He's a pilot." "Well, I have to chop it before he can pile it!"
