Fleming had kept samples of the original mold preserved between pieces of spectacle glass, which he proceeded to hand out to every dignitary who met with him. He was like the Oprah of mold samples. YOU get a mold! YOU get a mold! EVERYBODY GETS SOME MOLD! He gave so many to Prince Philip that the royal actually complained about it. And yes, he sounds like a crazy old man handing out bits of fungus, but in his defense those greenish blobs saved many millions of lives. Penicillin was the first modern antibiotic—suddenly doctors could treat bacterial infections. It was so valuable (and in such short supply) that physicians would collect their patients' pee to get back some of the penicillin that would otherwise go to waste. And given how many lives it saved, it probably ensured that your parents and grandparents survived long enough to produce you. So let's maybe not make too much fun of fungi.
