While on the subject of imbibing one's own urine I recall a story of survival in the Sahara Desert in Africa. Took place in the mid to late 1800s. A group of Brits ( who else!!) got lost while on some sort of expedition and survived for a while drinking their urine. Once it became too "strong" they switched to drinking their camel's urine which they claimed was much better. They were eventually rescued/kidnapped by some desert dwellers who they convinced to take them to the British consul in exchange for a reward. So a happy ending.
They may have been Americans so just switch Brits to Yankees if you want.
