"Sorry, but you're probably not as smart as you think."
John will never become self-aware. Pot(belly), meet kettle. He's incapable of realizing how much he highlights his own appalling stupidity when he says this sort of thing; Dunning-Kruger FTW. I also do not believe he's sorry in the least, other than in the sense of sorry-ass faggot.
This reassures me that he will never learn anything, or rise above his natural state of ignorance/idiocy. To paraphrase Lady Bracknell, "The whole theory of modern education is radically unsound. Fortunately, in John Flynt at any rate, education produces no effect whatsoever." He will continue to be a reliable target of mockery and derision for the foreseeable future, and may as well wear a Kick Me sign on his entire life.
