There was a show about the history of penicillin on PBS. A clinic in Florida was testing various molds and spores, then they found this strange blue mold that seemed to inhibit bacteria.
Either the sample got lost, or it wasn't very strong, whatever, they started to request oranges from around the world looking for the mold.
No luck. It was lost.
Then, one of the guys was walking around in downtown Miami or whereever, and stopped at a fruit stand.
One of the oranges had this funky blue mold on it. It was what they were looking for.
Penicillin has saved millions of lives.
I thought that's what I said in 13.
