KO'd, explain to everyone who was watching that the guy who KO'd you was playing dirty, spread rumors about how you were going to hit him back but your sorta-not-really boss won't let you because you would probably decapitate him AND all his friends with one punch, then wait two months and quietly throw a pen cap at him in the middle of a crowded hallway that makes it indistinguishable that you even threw it.

Tale as old as time.
