Hawaii Five-0, Season 4

Mary:
I'll just call Child Protective Services and Joan will have to be placed in foster care for a while. I just hope that the trauma doesn't affect her cognitive development.

Steve:
"Cognitive"? You don't even know what that word means.

Mary:
You're a horrible uncle, you know that?

[Later, Steve walks into the Five-O headquarters with baby Joan strapped in a carrier. Danny sees him and starts laughing.]

Steve:
Is this funny to you?

Danny:
Yeah!

Steve:
So when you're through amusing yourself, I need you to wipe down and change her pads, please.

Danny:
[smirks] Not at all. I'm retired, you see. And it's gonna be way too entertaining to see Uncle Steve on diaper duty, so go ahead.

Chin:
Hey, why is there a baby attached to your chest?
