Amitabh Bachchan recalled on Kaun Banega Crorepati that his wife Jaya once affectionately called him 'Lambu ji', but his late father Harivansh Rai Bachchan advised her to use his name instead. The actors also joked about height differences, and Amitabh said he is about 6 feet 2 inches, while Jaya measures roughly 5 feet 3 to 4 inches.
