Big B's wife, actress Jaya Bachchan has her roots in West Bengal, and she often talks to Big B in Bangla when she has to convey something very personal and specific to him while they are surrounded by people. However, Big B understands too little of whatever she says during these conversations as he has a very limited proficiency in the language.

On Kaun Banega Crorepati, Amitabh Bachchan shared how he learned Bengali during his early career near the Bengal Chamber of Commerce, managing to pass an exam despite limited formal training.

Amitabh Bachchan revealed that he doesn't understand what Jaya Bachchan tells to him but pretends to understand it all.

Amitabh Bachchan hilariously recalls feeling anxious during Jaya Bachchan's Bengali call, admitting he had to fake understanding!
