An american, an englishman, an Australian and an Afghan are all in a light plane together, flying over the Himalayas.
They eventually reach a large mountain, and there is too much weight aboard the plane to fly high enough to get over the mountain. The pilot says 'We are carrying too much weight, one of you's will have to jump off!' So the american guy says, "I'm doing this for my country." He then jumps out of the plane, and falls to his death.
They make it over the mountain, just to find a larger mountain on the other side, and once again there is too much weight aboard the plane to fly high enough to get over the mountain. The once again pilot says, 'We are still carrying too much weight, one of you's will have to jump off!' So the englishman says, "I'm doing this for my country." He then jumps out of the plane, and falls to his death.
Once again, they make it over the mountain, and once again there is another mountain on the other side, larger than all the rest. Once again there was too much weight aboard the plane to fly high enough to get over the mountain. Once again pilot says, 'We are still carrying too much weight, one of you's will have to jump off!' So the Australian says, "I'm doing this for my country." He then grabs the Afghan and throws him out, making him fall to his death.
