Amitabh Bachchan’s 83rd birthday celebration on Kaun Banega Crorepati saw him recreate his iconic ‘Zanjeer’ dialogue for guests Javed and Farhan Akhtar. The veteran actor’s powerful rendition, “Jab tak bethne ko naa kaha jaaye, sharafat se khade raho. Yeh police thaana hai, tumhare baap ka ghar nahi,” left the Akhtars astonished.
