As good as his IQ, Amitabh Bachchan also has a great sense on humour.

We hear, the actor picked on Amrita Rao, who is currently shooting for two films at a time. While she is shooting for Prakash Jha's film during the day, at night she shoots for Anil Sharma's.

In a very good mood Big B, while shooting for Jha's film told his co-stars Arjun Rampal and Ajay Devgn to buckle down and sign more films like Amrita.
