A University of Wisconsin–Stout theater professor, James Miller,has come under fire after putting up a poster for the Joss Whedon sci–fi western cult classic, Firefly, on his office door.

The poster (seen here) included one of Captain Malcolm Reynolds’ (Nathan Fillion) many classic quotes: “You don’t know me, son, so let me explain this to you once: If I ever kill you, you’ll be awake. You’ll be facing me. And you’ll be armed.” But apparently there’s a lot of very stupid people involved with monitoring the happenings of The University of Wisconsin–Stout, because campus police saw the poster, blindly only saw the words “kill you,” and removed it because clearly some kid was going to wander by, see it, and kill someone.

Nathan Fillion, current star of ABC’s Castle and formerly of Firefly/Serenity fame, decided to share a recent encounter he had with a fan via his Twitter account:

“Had a guy approach me on street. All he did was nod and say, “Captain.” That’s all he needed to say.”

For those of you who didn’t catch it, the fan was clearly referencing his character Malcolm Reynolds, captain of the firefly-class spaceship Serenity in the movie of the same namesake.

Depressing as it may be, Fox and whoever else that has had the opportunity have still not realized the must-happen decision that needs to be made to bring Firefly back from the dead. Proving that even the actors involved in the show are just as faithful to that “you can’t take the sky from me” mentality as us crazy Browncoat fans, Captain Malcolm Reynolds (Nathan Fillion) himself has been bringing plenty of Serenity flare to his current gig, Castle. It began with random and subtle references to Firefly as well as other Joss Whedon work like Buffy, but in the latest episode of Castle, Fillion took to a whole new level.

You see, this week’s episode was the Halloween episode, and what better costume for Richard Castle — the mystery novelist-turned NYPD aide — than Captain Mal? The episode is hilarious right off the bat with Fillion getting his costume on and jumping into a room like a superhero where a girl who I assume is his daughter says “Didn’t you wear that like five years ago? Don’t you think you should move on?”, to which he replies “I like it.”
