Castle, Season 6

Castle:
[Glossing over his bulletproof vest] Wow. And to think you boys mocked me when I had this made four years ago. I think I'll have it framed.

Ryan:
Hey, what does it say about your writing when your number one fan tries to kill you?

Castle:
That was an accident.

Esposito:
Been one inch high, it would've been a tragedy.

Castle:
But on the bright side, your autographed copies of Deadly Heat would be worth way more.

[Ryan snaps his fingers as Beckett walks in]

Beckett:
Not funny, Castle.

Castle:
Little bit funny.
