Euler-lagrange Memes

The mathematical equivalent of using a sledgehammer to kill a fly! This "proof" of the Euler-Lagrange equation is pure mathematical blasphemy that would make Euler roll in his grave at 9.8 m/s². The author commits the cardinal sin of calculus by casually swapping differentials like they're Pokémon cards, then boldly declaring "Because obviously:" before writing some truly cursed math. Then they cancel terms with the mathematical rigor of a toddler erasing homework mistakes. The punchline redefining Q.E.D. as "Questionably Established Derivation" instead of the traditional "Quod Erat Demonstrandum" is *chef's kiss* perfect. And publishing in "Totally Real Physics Letters"? That's where all my rejected papers go too!
