Class and Ass

Professor Laurie of Glasgow put his notice on his door: "rofessor Laurie will not meet his classes today."

A student, after reading the notice, rubbed out the "c".

Later Professor Laurie came along, and entering into the spirit of the joke, rubbed out the "l".

班和笨驴

格拉斯哥的劳里教授在门上贴了这样一个通知：“劳里教授今天不见他的班级。”

　　一个学生读了通知后，擦掉了字母“c”(lass：姑娘)。

　　后来劳里教授来了，也想开开玩笑，他擦掉了字母“l”(ass：笨驴)。
