A new lecturer walked
into a class one morning
and after greeting the
students, he asked, "Do
you know what we are
going to be teaching
today?"
The students all chorused,
"No Sir!"
Then he said, "Then there's
no point teaching you
what you don't know."
and he left.
The next day, he came in
and asked, "Do you know
what we are going to be
teaching today?"
They all answered, "Yes
Sir!"
Then he said, "Then there's
no point teaching you
what you already know."
and he left again.
The third day, he came in
and asked again, "Do you
know what we are
teaching today?"
Then the students
answered randomly, some
saying yes and some
saying no, then the
lecturer said, "Those that
know should teach those
that don't know", and he
left.
One word for this lecturer.
