Khan Sir and Zakir Khan are set to appear on Kaun Banega Crorepati 15. In a promo, Khan Sir humorously uses physics to describe their personalities, leading Amitabh Bachchan to comment, "Aapne jo abhi padhaya hai, wo hum zindagi bhar nahi bhulenge." Both are self-made icons, known for teaching and comedy respectively. Their episode airs Monday.
