“Just really quickly, if you know me, and you guys - you know me, you know that I don’t like to learn anything. But despite my best efforts, I have learned in 100 episodes how much I rely - on how heavily I rely - on all of you. When people tell me, and they do, that they love this show I don’t think of the polished piece that we see on TV, I think about the hours we pull, the freezing outside, the laughs, hanging out, and being here. And I appreciate you all, and I look forward to coming to work and being with you all, all the time. Thank you very much.”

- Nathan Fillion speech to the cast and crew of Castle during the party for the 100th episode
