Question

工程师逃票
有三个工程师和三个会计一起去外地开会，上火车时，三个会计买了三张车票，而三个工程师却只买了一张票，会计们很疑惑，就问工程师为何只买一张票，工程师说：“上了车你们就知道了。”
火车刚一开动三个工程师就挤进了一个厕所，列车员开始检票，最后走到了厕所外边，她敲了一下门说：“检票。”然后门开了一个小缝，从里面递出一张车票。
在外地开完会返回的时候，会计们觉得工程师们的方法很不错，于是也只买了一张车票，而这次工程师们一张票也没有买，会计们又很不解，工程师还是说：“上了车你们就明白了。”
上车之后，三个会计马上挤进了一间厕所，而三个工程师挤进了车厢另一边的厕所，火车开动不久，一个工程师从厕所里走出来，来到了会计们的厕所外面，敲了一下门说：“检票。”
