I'm nobody! Who are you?
我啥也不是,你呢?
Are you nobody, too?
牛逼如你也是无名之辈吗?
Then there's a pair of us - don't tell!
那我们就是天生一对,嘘!别说话!
They'd banish us, you know.
你知道,我们不属于这里。
How dreary to be somebody!
因为这里属于没劲的大人物!
How public, like a frog
他们就像青蛙一样呱噪,
To tell your name the livelong day
成天将自己的大名
To an admiring bog!
传遍整个无聊的沼泽!
