I don't think I could pick his knees out of a lineup.

估计你让我在一堆人里认我都认不出他的膝盖。

The Avalanche goalie? - Yeah, he's out. Knee problems.

－雪崩队的守门员？ －是的，他不能上场，因为膝盖受伤了。

" Supersonic man out of youuuu, " Alex mumbles low, craning his head back into Henry's ear, and Henry laughs and kicks his knees out from under him

“来自youuuu的超音速人， ” 亚历克斯低声咕哝着，把头伸回到亨利的耳边，亨利大笑起来， 把膝盖从他身下踢了出来。
