- 1898, 溫斯頓·丘吉爾, 章号 1, 出自 The Celebrity:
  I was about to say that I had known the Celebrity from the time he wore kilts. But I see I will have to amend that, because he was not a celebrity then, nor, indeed, did he achieve fame until some time after I left New York for the West.

- 2013 July-August, Henry Petroski, “Geothermal Energy”, 出自美國科學家, 第 101 卷, 第 4 期:
  Energy has seldom been found where we need it when we want it. Ancient nomads, wishing to ward off the evening chill and enjoy a meal around a campfire, had to collect wood and then spend time and effort coaxing the heat of friction out from between sticks to kindle a flame.
