Get out !!!!!

I was in my 6th semester when this happened. It was a basic mechanical engineering hour. I really don't know the reason why we electronics students had to learn a mechanical engineering paper in 6th semester. I had lost all the touch with the subject. It was in my 11th standard that I had learned something similar. So let's come to the point. Dinesh sir, asst professor of ME department was assigned in our class. We were much advanced in learning, as we used to research on how aeroplanes fly depending on their aerodynamics. It was like a free period for us. In his class, he made it mandatory that every student should bring a calculator but we made it mandatory that every five persons should have a calculator. He always wanted us to shout answers. But we knew it was wrong to shout in class, so we kept mum. On one fine day, when he was doing a problem and he provoked us to shout answers. We obliged. Every body was shouting their own answers. Sexy answered "28.86". Rajeev didn't agree. He said "28.87". They were playing some kinda cricket. Then preju, mammootty, aadu and all came up with their own answers and joined them. The class was going out of his control. I and Srihari, were sitting with them. We were enjoying all the procession. We couldn't control our laughter. We suddenly broke into it. Suddenly our teacher turned back and saw us laughing. We didn't even have the notebooks. He yelled at me, "GET OUT"!!! I was trying to explain him, what really happened. Then he saw Hari chuckling. He roared' "you too". We made our walk out of the class as if we had hit a double century in 20-20. Well, after the class we went to apologise to him. He advised us and then pardoned us. As started strolling away from him, he called us from behind and asked, "what are your roll numbers, i have to mark attendance for you people". We were stupefied that a teacher in LBS was so liberal.
