Author James Thurber depended on words for entertainment. He told me once about a trick he played on a nurse during one of his hospital stays. He asked her what a seven-letter word had three U's in it. She thought and then said, "I don't know, but it must be unusual!" 作家詹姆士·瑟伯用词来消遣。 他曾经告诉我有一次住院时在一个护士身上所开的玩笑。他问她哪一个7个字母的单词有三个U。她想了想，然后说：“我不知道，不过这个单词准是unusual（异乎寻常的）！”
