Sometimes, we'll say that the strike zone changes. It changes because Major League Baseball redefines it, or because umpires subtly and collectively shift on their own over time, or for the situation at hand, or based on the way that the catcher receives the ball. The strike zone is a social construct of a social construct, and it's even squirrelier than you think. Want to try calling pitches? Okay, I'm going to show you five pitches and tell you whether I believe they're a ball or a strike. You call the sixth and seventh.
(Keep in mind that this particular umpire is unusual but not unpredictable. Also: This post is a riddle.)
