Amitabh Bachchan, the iconic figure of the Indian cinema, experienced a wave of nostalgia during `Kaun Banega Crorepati 15` when a contestant revealed staying in the same college hostel room in which he did. This delightful connection sparked memories of Amitabh`s Kirori Mal College days, taking him on a trip down memory lane.

Big B, who is the host of the quiz-based reality show, welcomed Avinash Bharti to the hot seat. He hails from Haiderganj, Uttar Pradesh. During the game, the megastar shared that the makers of the show have shot a video of Avinash. In the video, the contestant says: “I hail from Haiderganj in Uttar Pradesh. I currently live in Delhi on rent and am preparing for UPSC exams. My family underwent many hardships for me. I want to do something for them.”
