Point Taken

Overheard at the library where students were busy with the registration of the subjects they enlisted.

Professor L: Let's see. *Scans the form* So you failed in this subject last year.
Student: Yes sir.
Professor L: Which is why you have to take it again.
Student: Yes sir.
Professor L: So, who was your professor for this subject?
Student: *Gives the professor's name*
Professor L: I see. So, what did you learn from him?
Student: That's exactly the point, sir.

Kumbaya.
