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: What is that smell?
Casey: That is the stench of tyranny.
Chuck: I don't think I'm really cut out for a job where you disarm a bomb, steal a diamond and then jump off a building.
Sarah: Well, you could have fooled me.
Chuck: That's very kind of you to say, but I'm pretty sure my girlish screams in the face of danger give me away.
