What a funny class rep

A lecturer was teaching his students in a Philosophy
class and he told them that there is no God.
Trying to prove his point, the lecturer took the
students out and asked them to look up the sky.
LECTURER: Look at the sky very well
STUDENTS: We are looking
LECTURER: Ok, what do u see.
STUDENTS: Cloud
LECTURER: Do u see God?
STUDENTS: No............
LECTURER: which means there is no God (after that,
they went back to the class.
LECTURER : any question?
CLASS REP: I have a question sir.
LECTURER: Yes go on
CLASS REP: Sir can u pls remove ur cap?(Teacher removes his cap)
CLASS REP: Students look at his head very well and
tell me what u see?
STUDENTS: We can see his hair, skin and so on.
CLASS REP: Did u see his brain?
STUDENTS: NO
CLASS REP: That means our lecturer has no brain.....
STUDENTS : Yes ooooooo(Chorus together)
Is the class rep right or wrong?
