Zachary Levi stars as the title character Chuck Bartowski on NBC's amazing dramedy, Chuck. Chuck is a nerdy guy that ended up working at the Buy More nerd herd desk after he was kicked out college at Stanford.
Chuck's former college roommate, Bryce, ended up sending him an encrypted email which contained a program known as the Intersect. Once the Intersect was in Chuck's brain, he became extremely useful to both the good guys (the CIA / NSA) and the bad guys, Fulcrum.
Both the CIA and NSA sent agents, Casey and Sarah to protect him and now Chuck has to lead a double life as both a Buy More employee and a secret agent in order to keep his family from finding out.
Chuck: Are you enjoying this whole Martha Stewart thing? (laughs) I can't believe it. Please tell me you're not going soft on me.
Sarah: Just shut up and eat your breakfast.
Chuck: You better be careful, Sarah. One day, you might actually turn into a real girl.
Mark Ratner: See, I'm just a guy who likes math, you know, and somehow I got a beautiful girl like that to fall in love with me. I have to pinch myself sometimes. It's like I'm dreaming.
(Chuck's eyes meet Sarah's from a distance. A smile washes over her face)
Mark: Aw, forget it, Agent Carmichael. I mean, how can I expect a cool guy like you to understand?
Chuck: You know what, Mark? Sometimes the nerd gets the girl.
