Read: Amitabh Bachchan on if asked to become President

Mumbai: Amitabh Bachchan, who has been in the filmdom since long, was recently asked a strange question by filmmaker Karan Johar, which surely surprised the Bollywood megastar.

The film industry icons were talking at an event when Karan asked Big B what would he do if asked to become President of India.

Big B, with all his gentleness that he always possesses, replied, "This is a very old joke first cracked by Shatrughan Sinha. Have a look at me, do you really think? C'mon... no worthiness, no capability, no knowledge..."

Karan, who is widely popular for his wicked questions that he asks his celebrity guests on his talk show "Koffee With Karan", this time took Big B with surprise.

The two, however, have worked together in iconic movies like "Kabhi Khushi Kabhie Gham" and "Kabhi Alvida Naa Kehna".
