This speech is definitely a very different one from the usual style of Thenkachi Ko. Swaminathan(Indru oru thagaval fame).
Generally, he speaks about saints and some spiritual matters and then he'll start telling a comedy story regarding that.But in this part of speech, he took a topic "our character determines our profession" and tells simply jokes on it. He took a doctor,Engineer, Lawyer and physics, maths professors as characters. This speech took place at Annamalai university function. So, he handled the speech very lightly ,as the spectators are students.
Just laugh friends...
