来个英语小笑话

学了那么久英语，是不是经常会出各种洋相？这里我们来一个英语小笑话，看看别人是如何搬弄文字的？

Class and Ass 班和笨驴

Professor Laurie of Glasgow put his notice on his door: "Professor 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)。
