They think they're your most precious possession, they are calling themselves 'human capital' for God's sake! A 'human capital error', that's what they are! So if one of those arrogant pricks comes barging into your office, threatening to resign that shitty job you tolerate them in, this is your chance:

You stand up, walk up to them, look them straight in the face without any expression on it, spit out a gob of chewing tobacco right over their shoulder, slowly stick out your hand and say: "So you want to resign, eh? Well, punk, make my day!"
