Maxwell Smart is the brains (sort of) behind Get Smart. He's the main referred to in the title of the movie, as everyone is out to get him. Doesn't seem like it should be that hard, of course. Maxwell Smart isn't the most intelligent spy on the planet.
Maxwell Smart: [after he gets recruited as a new agent] I request a cone of silence. Maxwell Smart: [he doesn't press the button hard enough so everyone can hear him] Oh, I'm so happy! I'm so happy! This is the best day of my life! Lloyd: Dude, you didn't press the button hard enough... Maxwell Smart: Right.
