An Idea to send the lecturer packing

Gopal was a college student
And he lacked patience
To listening to boring lectures
From aged absent minded professors.

Gopal was sitting in afternoon class
Struggling to avoid falling asleep
Suddenly the professor got a call from office
And he had to leave the place.

Gopal sighed with relief
But professor came back to class
And inquired “Now, where was I?”
Instantly Gopal replied, “Right near the end!.”
