My father would tell a story explaining why one foot was scarred and ticklish that involved the neighborhood kids pissing on his bleeding foot after stepping on a broken bottle while playing soccer barefoot in the plaza back home in Italy. All the kids knew to piss on the wound to sterilize it. He was born in '42.

And Lawrence of Arabia in the Seven Pillars of Wisdom. In which the young men piss on wounds.

"The other wounded men were seen to at the same time. Mifleh brought up the youngest lads of the party, and had them spray the wounds with their piss, as a rude antiseptic."
