A notoriously absent-minded professor was one day observed walking along the street with one foot continually in the gutter, the other on the pavement.

A pupil meeting him said:

"Good evening, professor. How are you?"

"Well," answered the professor, "I thought I was all right when I left home, but now I don't know what's the matter with me. I've been limping for the last half-hour."

心不在焉在老师

有一天，人们看见一个有名的心不在焉的老师在路上走，他的一只脚一直踏在街沟里，另一只脚踩在人行道上。

一个碰见他的学生说：

“晚字，老师。您怎么了？”

“啊，”这位老师回答说：“我想我离开家的时候还挺好的，可是现在我不知道出了什么毛病。我已经一瘸一拐走了半个小时了。”
