Chuck, Season 2

Sarah:
You know, Chuck, Casey is right. You could've gotten yourself killed. What exactly were you thinking?

Chuck:
What was I thinking? I'll tell you what I was thinking. I was thinking like I wasn't a spy. Okay. I was trying to have a little bit of fun. And I knew the second I called you two, it would all be over!

Sarah:
But Chuck, you are a spy. And you should know better than to put yourself in a dangerous situation where I can't protect you!

Chuck:
Is it really so wrong for me to want a night off? I was having a really good time, too, until the assassins stole my pants and tried to kill me. I've earned it. I deserve it.

[Casey shoots him with a tranquilizer dart]

Chuck:
I'm losing consciousness.

[Chuck falls to floor unconscious]

Sarah:
CASEY!

Casey:
My ears couldn't take it. Either that or I shoot him.
