I saw an interview with him once where he was describing his Bond... I can't find it exactly, but it went something along the lines of "This guy is supposed to be the best secret agent in the world, yet he walks into a room and the main target of his investigation says 'Aaah, Mr Bond! I've been expecting you!'. You can't take that guy seriously. So I didn't."
I think he was certainly the most fun Bond out there. RIP, Sir Moore.
Edit because oh yeah, Knight!
