Chuck: [Text message to Sarah and Casey] I also unlocked your door. Taking them to Buy More. Unleash the Casey.

Chuck: [the flight attendant pulls a weapon on Chuck] I am so writing a letter to the airline about this.

Chuck: [to Casey] We gotta get you reinstated, buddy. Without a license to kill you're a menace to society.

Chuck: [to Ellie] And I realize that Jill, Stanford and Bryce, that's a story from my past... But my new story is you, and Sarah, and these friggin yahoos. And sometimes it can be a real fun story.

Chuck: [to Noble and Dunwoody] So, are you guys a couple or something?
Rick Noble: Don't be ridiculous.
Victoria Dunwoody: It's against agency protocol.
Noble: Romantic entanglements lead to lapses in judgment.
Dunwoody: [to Chuck and Sarah] You ought to know.

Chuck: [to Sarah and Casey dressed as nerds] Either this is a mission or you two are very good at hiding your hobbies.

Chuck: [to Sarah, after Casey's pep talk] I don't need a balcony and I don't need a sunset. We have each other and that is all that matters.

Chuck: [to Sarah, under the influence of a truth serum] God you're so pretty! And Casey, your jaw was chiseled by Michelangelo himself.
Casey: Thank you.

Chuck: [to Sarah] Do our wedding colors remind you of socialism?

Chuck: [to Sarah] Look, I'm not accusing you of anything...today. Yesterday yes, I may have laid it on a little thick with the accusing. But I'm really sorry about that. Instead of not trusting you I should have been thanking you for saving my life and protecting the country and for making really tasty gourmet wieners.

Chuck: [voice-over] My name is Chuck Bartowski, and if you're reading this, it means I'm already dead. I don't know what will end up killing me but I've chosen to be a spy, and there are consequences to that. It may be my emotions that end up doing me in or a slip-up, trying to protect my friends or my family who never wanted me to be a part of this. Or it could be the thing I never saw coming, but I know it's coming.

Chuck: [watching Lester's sales policy in action] That's gonna end badly.
Morgan: I know. I know, Chuck. That's part of the fun.

Chuck: [while on a date with Lou] It wouldn't be an official Chuck Bartowski date if the woman didn't leave injured in some way.

Chuck: [while Sarah is about to leaving for a mission] What am I, what do I say? What do we...?
Sarah: I love you.
Chuck: That's good. I love you. I like that. I love you, too. Be safe, okay?
Sarah: Nothing is gonna keep me from coming back to you.
Chuck: Better not.

Chuck: And the decision I made in Prague. I know what it looks like, I know that it looks like I chose being a spy over-over being with you. But that's not what happened. How I felt about you was real. Very, very real. And I know that you know how I felt about you for a long time, you know. But when Carina told me what you said, those three words that I waited to hear for so long. Look Sarah, I know. You were probably very hurt. Probably hurt that I didn't run away with you in Prague... Sarah, I love you.
