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".
"I always feel that he has the most heartiest laughs that we could find in any human being. A laugh really represents what a person is, that's what I believe," he said.
