The story is told of two hunters who hired a pilot to fly them into the far north for elk hunting. They were quite successful in their venture and bagged six big bucks. The pilot came back, as arranged, to pick them up.
They started loading their gear into the plane, including the six elk. The pilot objected and said, "This plane can only carry four of your elk. Any more than that would overload the plane drastically. You'll have to leave two of the elk behind." The two hunters were both infuriated and insistent. They said, "Last year, we shot six elk and that pilot let us put them all on board and that plane was the exact same model."
Reluctantly, the pilot finally permitted them to put all six aboard. But about fifteen seconds after a reluctant take-off, the engine started to sputter, and within seconds they started dropping rapidly to the ground and crashed into the wilderness. Climbing out of the wreckage, one hunter said to the other, "Do you know where we are?" "I think so," replied the other hunter. "I think this is about a quarter mile from where we crashed last year!"
