They're basically on, like, two or three milli-... Or three or four millimetres of metal, that's all that's holding them up.

他们基本是踩在，比如，两三毫—… 或三或四毫米金，就是所有够撑起他们西了。

Two milli... that doesn't seem right.

两毫...不太可吧。

I don't care. Two milli ... that doesn't seem right. No, it's true. I did a series of experiments when I was 12. My father broke his clavicle.

不关我事。2毫米？不会吧！是真，我12岁时做了一系列实验，我爸爸因此还跌断了锁骨。
