According to the Bible, it rained for forty days and forty nights, and Noah was begining to worry about the stability of the Ark. Although he had very little formal education, he understood that all the large animal manure piling up was creating an unstable ship. To correct the problem he issued shovels to "all hands" including all the monkeys and apes, who shovelled over the side all the animal shit; and there it lay till Christopher Columbus discovered it.
