One looked at the other and said, "I've got to take a shit."

其中一个人对另一个人说，“我要去拉泡屎。”

But its hard to relieve yourself, to take a shit, you cant do it on the train, and the only time the train stops is to take on water for the locomotive.

这几乎不能让你感到好受些，你不能在火车上方便，唯一的机会是在火车停下来为机车加水的时候才可以。

F4's Ken Chu wrote on his Sina Weibo micro blog the reunion would not take place because of a "mouse shit".

F 4成员朱孝天在自己的微博中表示，F4难以重聚的原因是“有一颗老鼠屎在”。
