In a conversation comparing the wordplay, linguistic innovation, and quotability of Joss Whedon (Buffy the Vampire Slayer, Firefly, Serenity) and William Shakespeare (Macbeth, Hamlet, Much Ado About Nothing):
M: "...Of course, Whedon's soliloquies do tend to be shorter."
J: "Well, you know what they say about brevity..."
M: "'The soul of wit', yeah?
J: "Ooh, I like that! It's catchy."
