Acetaminophen Memes

Two chemists brag about their 99.57% and 99.95% yields, calling each other amateurs. Then a mysterious hooded figure shows up with a physically impossible 357.69% yield. For the uninitiated: chemical yields over 100% are theoretically impossible since you can't create matter from nothing. A yield this high means either serious contamination, analytical error, or... dark magic. Every organic chemist knows that person who somehow breaks the laws of thermodynamics in lab. They either don't exist or should be immediately recruited by CERN.
