A couple of hunters chartered a small plane to fly them to a forest,and made an appointment with the pilot to come back and
fetch them in about two weeks. At the end of the two weeks, they had shot a lot of animals that they wanted to load onto the plane. But the pilot said, "This plane won't be able to take more than one wild buffalo. You'll have to leave the others behind."
Then the hunters protested, saying, "But last year, another pilot  with the same airplane let us take two buffalos and some other  animals in the plane as well."So the new pilot thought about it. He was a little bit skeptical, but finally he said, "OK, since you did it last year, I guess this year we can do it again." Then he loaded the two buffalos and a few other animals in, and the plane took off. Five minutes later, it crashed in a neighboring area.The three men climbed out and looked around, and one hunter said to the other, "Where do you think we are now?" The second one surveyed the area and said, "I think we're  about one mile to the left of the place we crashed last year."

同样的行为，同样的结果
有两个猎人包机前往一座森林，到了以后，他们和飞行员约定好两周后来接。两周后，他们射了许多动物，而且打算把这些动物全部搬上那架小飞机，可是飞行员说：「这架飞机除了一头野牛外，没办法再多载了。

你们必须把其他的猎物都留下。」猎人说：「但是去年另一个飞行员开一样的飞机，就让我们带两只水牛，还有一些其他的动物上机！」因为他们这样抗议，所以那个新飞行员想了一想后，尽管还是有点存疑，最后还是妥协说：「好吧！如果去年可以做到，今年应该也可以。」所以他装了两头水牛和一些其他的动物。结果飞机起飞五分钟后，就坠落在邻近的地方。这3个人从飞机爬出来看了看四周，其中一个猎人对另一个说：「你认为我们现在在哪儿？」那个人瞧了一下，说：「我想大概距离去年坠机的地方西边一英哩远！」
