Assumptions: A couple of hunters chartered a plane to fly them into forest territory. Two weeks later the pilot came to take them back. He took a look at the animals they had shot and said, “This plane won’t take more than one wild buffalo. You’ll have to leave the other behind.” “But last year the pilot let us take two in a plane this size,” the hunters protested. The pilot was doubtful, but finally he said, “Well, if you did it last year I guess we can do it again.” So the plane took off with the three men and two buffaloes. But it couldn’t gain height and crashed into a neighbouring hill. The men climbed out and looked around. One hunter said to the other, “Where do you think we are?” The other inspected the surroundings and said. “I think we’re about two miles to the left of where we crashed last year.” 🙂
