Would you pee on a friend's wound?

Back when antisceptics weren't a household commodity (and even today, wherever antisceptic isn't found in a bottle on the shelf), human urine was the disinfectant of choice. Pity the villager who gets bit by a snake just as soon as he's done taking a leak. His only hope would be for a true friend to happen to be just passing by, so he can bless his pal with some fresh warm brine.
