This idiom comes from an actual incident in which playwright and critic John Dennis(1657-1734)devised a"thunder machine"(by rattling a sheet of tin backstage)for his play,Appius and Virginia(1709),and a few days later discovered the same device being used in a performance of Macbeth,whereupon he declared,They steal my:hunder

尼斯（1657-1734年）为其戏剧《阿匹乌斯和弗吉尼亚》发明了一种&雷声机&(通过在后台抖动一块锡器)，但是几天后，他发现这一机器被用在了戏剧《麦克白》的上演中。因而他声称&他们偷了鸯，的雷声&。
