When contractors said some of Boyd’s engineering specifications could not be met or that a fighter could not do what Boyd wanted it to do, he listened, chewed on his hand, and stared unblinkingly at the contractor. When he had enough he stopped chewing, spit out pieces of skin, jabbed the contractor in the chest, and exploded. “You are the dumbest son of a bitch God ever made” or “You don’t know what the fuck you’re talking about” or “You stupid fuck. That will never work.”
