Boman Irani: Dr. J. C. Asthana
Dr. J. Asthana : Are there any questions?
Murli Prasad Sharma : Yes, sir... If a man is dying in the admission ward, is it necessary for him to fill our a form?
[a shocked Asthana dismisses the class, but the next day... ]
Murli Prasad Sharma : Sir, I asked you a question yesterday that you didn't answer - can't you answer it today?
Dr. J. Asthana : Mamu, he called me MAMU!
[Mamu means "dude" and/or "doofus"]
