Just watching him and being in his company is a great revelation," the 70-year-old actor told reporters here Thursday.
"I always wonder how he remembers all these wonderful quotes. I am truly impressed and I wish I could use some of them in my show KBC," added Big B, who hosted the game show.
Big also admires Sidhu's "heartiest laughs".
