Class, Lass and Ass¹

Professor Tom was going to meet his students on the next day,  so he wrote some words on the blackboard which read as follows: "Professor Tom will meet the class tomorrow."

A student, seeing his chance to display his sense of humor after reading the notice, walked up and erased² the "c" in the word "class." The Professor noticing the laughter, wheeled around, walked back, looked at the student, then at the notice with the "c" erased--calmly walked up and erased the "l" in "lass", looked at the flabbergasted student and proceeded on his way.

班级、情人和蠢驴

汤姆教授打算第二天与他的学生见面，因此他在黑板上写道：“汤姆教授明天将和大家见面”。

一位学生看到这条通知后，觉得展示自己幽默感的机会来了，就走上前，将“class”中的“c”擦掉，将意思变为“汤姆教授明天将和情妇见面”。教授听到笑声，转过身走回来，看了看那位学生，又看看被改动过的通知，不动声色地走上前，把“lass”中的“l”擦掉，将意思改为“汤姆教授明天将和蠢驴见面”。看了看那位目瞪口呆的学生，教授扬长而去。
