One night in 2003, Jim Carrey was on
Conan's Late Show on
NBC. Carrey mentioned he was reading Hawking's new book and began sharing with the audience Hawking’s theory in detail when the phone rang and Hawking himself urged him to stop "Their Pea brain can’t grasp the idea", He said. Then Carrie tells him he's a genius and Hawking replies "No, you're a genius" and they kept complimenting each other until Hawking says "Well, I'm busy watching Dumb and Dumber" and hangs up.
