The mathematical rebellion is real! This "proof" hilariously satirizes the famous (and legitimate) result that claims the sum of all positive integers equals -1/12—a mind-bending conclusion from analytical continuation in string theory.
The punchline is in the absurd logic: "Why 13? Because I like it and this is my paper." Pure mathematical anarchy! It's the equivalent of saying "2+2=5 because I'm having a bad day." The creator brilliantly mocks how easily mathematical notation can be manipulated to "prove" nonsense when you ignore the rules.
Even the smug "Q.E.D." at the end (Latin for "thus it has been demonstrated") is the chef's kiss of mathematical satire. Mathematicians everywhere are either crying or laughing uncontrollably.
