Wife told me the other day that she hadn't drunk any water and her pee smelled like coffee. It gave me an idea. You know how they feed coffee beans to civets then sell the civet shit as expensive gourmet coffee? Maybe we could do the same with girls. Make them drink tons of coffee with no water and collect the piss. Eat whatever you want, but no water at all. Don't give a fuck if you are crippled by muscle cramps. I imagine that would taste pretty much like pabst blue ribbon mixed with cold coffee. So you have an automatic market with hipsters and other pee drinkers. But if you wanted to open it up, you could find the worst pee filtration method on the market and use that to clean it up.
Then I realized that they're probably already doing it in Japan and/or chyna.
