This is the most important line in the movie. I'm 100% serious. It tells you everything you need to know about Lex Luthor's character. It shows the audience that, despite being almost omnicognizant from the get-go, Luthor clearly has no fucking idea who Superman is, only what he does.

I've never seen anyone go from All-Knowing Evil to Absolute Fucking Loser so fast. In fifteen words he went from unstoppable criminal powerhouse to flailing manchild moron. He gave his Evil Dictator demonstration and then turned around, dropped his pants and showed his entire ass. He proclaimed his manifesto of unrelenting ego, turned around, slipped on a banana peel and landed on a whoopie cushion.

And he was so mired in his own sense of superiority that he never even knew it.
