Medieval mathematicians dropping the mic on proofs! The yellow-robed scholar starts with "Geometry is a scam," but then brilliantly demonstrates proof by contradiction - the backbone of mathematical reasoning. "Prove this is a triangle" followed by "Look at it. WTF else could it be?" is basically Euclid's Elements if he wrote them during a pub night. It's the mathematical equivalent of saying "if it looks like a duck and quacks like a duck..." except with theorems. Mathematicians have been using this savage technique since ancient Greece - assuming the opposite of what you want to prove, then showing it leads to nonsense. Pure genius wrapped in medieval sass.
