这个表达, 有人说,是源于德国十九世纪Richard Wagner's音乐歌剧The Ring of the Nibelung里的一个熟悉角色,名叫Brunnhilde,常常由胖胖女子扮演,在最后十几分钟或近二十分钟里压轴独唱(歌剧很长,长达14多个小时)。所以, 'When the fat lady sings' is a reasonable answer to the question 'when will it be over?'
但也有人说,不是这个典故,因为,印刷的文字记载表明是从1970s开始出现的, 源于一个叫Dan Cook的体育解说员, 在德州体育比赛时说的一句话“ The opera ain't over till the fat lady sings", 而广为流传的。
Anyway, 在讲述上述故事后,这个表达的意思就显而易见了。相似的表达有:
As long as the organ is playing, church is not out.
Don't count your chickens until they're hatched.
Nothing is carved in stone.
It ain't over till it is over.( Yogi-ism, 源自一棒球选手)(Thanks to "汤圆妈妈”)
