English Original
A young man in a village was considered a half-wit.
Whenever he was offered a choice between a dime and a nickel, he always chose the nickel. After this had happened many times, a kind old man explained that a dime was worth twice as much as a nickel, advising him to choose the dime in the future.
The half-wit replied, "Oh, I know the difference. But if I chose the dime, they'd stop offering me the choice, and then I'd never even get the nickel."

村子里有个年轻人，大家都认为他是个傻子。
每次有人拿出一枚一角硬币和一枚五分硬币让他选，他总是选那枚五分的。这样的事发生了很多次后，一位好心的老人告诉他，一角硬币的价值是五分硬币的两倍，建议他以后应该选一角的。
傻子回答说：“哦，我知道它们的区别。但如果我选了一角的，他们就不会再让我选了，那样我连五分钱都拿不到了。”
