Absent-minded professor:心不在焉的教授

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 student meeting him said:

"Good evening, professor. What's the matter?"

"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."
