The lecturer under the evil mask

Lecturers
Most are average, a hand full are good
Some are great and even cool!
They're poles of knowledge that holds up high
But there is one who is the student's foe.

From afar I see the man
The sinister smile I can't forget
Giving a speech so much like the pope
And says he loves us all the time:-
I don't know if that’s true.

No offense but sir, here's the truth
We're all dull with all your quotes and cites
The same line you used to tell us every time
We dare not show it but that is how we feel
To be thinking of you makes us ill.

I don’t really know if I am right
But for now, it seem too good to be true
Looks like it that many will agree
That you are "nothing more than"
The lecturer under the evil mask.
