Re: Castle Season 5 (including Spoilers)
Dropping Firefly directly would've been way too obvious though. I like how they got two subtle references in within a minute. Nebula 9 was a cult TV show that only got thirteen episodes but has a dedicated following, and when Castle is listing show's he mentions "that Joss Whedon show."
"If Romeo had just masturbated a couple of times a week he would have saved both those nice families a heap of trouble."
