Fresh Problem with the Ark

Let's say there were 22,000 species of animals on the Ark (I got that number somewhere and I'm certain it's conservative)in pairs, that would be 44,000 animals...lets say each animal (on average) urinated 1 fl. oz. per day (again conservative (elephants and horses, dogs and cats urinate a lot more than that, where as birds, lizards and small snakes probably urinate about that))...with 128 oz's in a gallon that would come out to about 344 gallons of urine per day times forty days...uhmmm...cypher...cypher...thats 13,760 gallons of piss...Noah must've had one huge port-a-pottie on the ark!
