Yoneda lemma Memes

Math professors really be out here prescribing meditation disguised as homework! The Yoneda lemma is notoriously abstract in category theory, and this prof's solution is basically "stare at it until enlightenment hits." It's the mathematical equivalent of "have you tried turning your brain off and on again?" The best part is that it actually works—after hour 7 of staring, the proof either becomes crystal clear or you hallucinate understanding. Either way, problem solved!
