Proof by Violence
Dialogue
Overview
This meme uses the classic retro Batman slapping Robin comic panel. Robin states he has found the largest prime number, and Batman slaps him while saying "+2". The joke plays on the mathematical proof that no largest prime number exists: if a number p were the largest prime, p+2 would either be a larger prime or have prime factors larger than p, immediately disproving Robin's claim. The title "Proof by Violence" refers to Batman using physical force instead of a logical explanation to shut down Robin's mathematically incorrect assertion.
Origin notes
This meme originates from the Reddit Meme subreddit, sourced via RSS feed. It is remixed from the widely circulated "Batman slaps Robin" meme template, which comes from the 1965 DC Batman comic issue #153. The template was edited to add dialogue referencing the mathematical prime number proof joke, and given the title "Proof by Violence".
