For anyone who watched Monday night's 'very special' Halloween episode of Castle, you were treated to a none-too-subtle shoutout to genre fans. The episode starts out with Nathan Fillion ("Castle") playing with quick-drawing and re-holstering a cool-looking pistol while wearing his old costume from "Firefly." (in which he played Mal Reynolds)
He busts in to his livingroom, gun drawn, and his daughter asks him what he's supposed to be. "I'm a space cowboy."
"One," she replies, "There are no cows in space, and two, didn't you wear that thing like five years ago?"
