At a street price of $20 for a small bottle, Purell is trading at about 1500x the price of crude oil. I know the window closed a while ago on getting things like laws and ratios named after oneself — and everything’s already been thought of, anyway. No matter, I’m planting my flag because this will be a useful indicator for a long time to come: Purell:crude = Byfield’s Ratio. 🏴
