Professor Godwin,feeling unwell,wrote on his bedroom door this notice:"The professor will be unable to meet his classes this evening." A student rubbed out a letter and made it,"The professor will be unable to meet his lasses this evening." Godwin,perceiving this, turned the tables by striking off the next letter, and making the notice read;" The professor will be unable to meet his asses this evening.
參考答案:戈德温博士感到不舒服，于是写了张便条贴在卧室门上：“晚上博士不能来上课了。”一学生看后将一字母擦去，意思就变成了：“晚上博士不能来见他的情人们了。”戈德温博士看后，心生一计，又擦掉一个字母，最后便条的内容就成了“晚上博士不能来见他的蠢驴们了。”
（注：class班级；lass情人；ass蠢驴）
