battriangulation
Explanation
In this comic, Commissioner Gordon signals Batman using the Bat-Signal, and Batman arrives -- but the twist is that Batman explains how he found Gordon using mathematical triangulation. By repeatedly measuring the time to arrival from different signal activations, Batman can estimate his distance; by knowing the direction (determined from the helicopter's approach vector), he can triangulate Gordon's position.
Robin suggests they'll need "more complex" methods next time, but Batman assures him they can handle it. Commissioner Gordon's reaction: "Boy wonder, but we'll also need to address the long-term problem." The final panel shows a newspaper headline: "BRUCE WAYNE WITHDRAWS FUNDING FOR AFTER-SCHOOL MATH -- 'It's not useful in real life.'"
The title "battriangulation" is a portmanteau of "bat" and "triangulation." The joke works on multiple levels. First, there's the irony that Batman uses sophisticated mathematics (triangulation, approach vectors) to fight crime while his billionaire alter ego Bruce Wayne publicly defunds math education, claiming it's not useful in real life. This satirizes real-world politicians and wealthy figures who benefit from STEM knowledge while cutting education funding. It also plays on the common student complaint "when will I ever use this in real life?" -- the answer being, apparently, when you're a vigilante superhero. The comic cleverly critiques the disconnect between people who rely on technical knowledge and those same people (or their class) undermining public education.
