English Original
Someone asked a little boy: "Is a pound of lead heavier than a pound of feathers?" The boy quickly replied: "Of course it is."
When he was told, "You are wrong. They both weigh the same," he insisted that a pound of lead is heavier. He said: "To prove it, I would go up on the balcony and drop a pound of feathers on your head and then drop a pound of lead to let you say which is heavier."

有人问一个小男孩：“一磅铅比一磅羽毛重吗？”男孩立刻回答：“当然。”
当被告知“你错了，它们重量相同”时，他仍坚持认为一磅铅更重。他说：“为了证明这一点，我会到阳台上，先往你头上扔一磅羽毛，再扔一磅铅，然后让你说哪个更重。”
