Castle, Season 2

Jessup:
[Regarding his handcuffs] Hey, you guys mind if I take these things off? I'm starting to feel like a stereotype riding around in the back of a police car wearing them.

Beckett:
Sure. Do you want my key?

Jessup:
Nah, I got it. Thanks. [Undoes his handcuffs]

Castle:
How did you do that?

Jessup:
I've always been good with locks. When I was in the joint, I was thinking how can I take this and make it more productive, you know? So, I've been applying for locksmith schools, but, you know, they won't let me in on account that I'm a felon. Can you believe that?

Beckett:
A felon who wants to be a locksmith. What could possibly go wrong there?

Jessup:
You don't have to be mean about it.

Castle:
Yeah. Wow.

[Beckett glares, beat, Castle relocated to back seat with Jessup]
