The stories we know today as Aesop's Fable's were originally a manuscript written by a raving mad and quite perverted hermit named Uusap. The original book was quickly discarded by all who came across it until it ended up with a Quaker who (after bathing himself and asking for God's forgiveness) took out all of the pornographic ravings and replaced them with good wholesome morals.
This is the only known copy of one of the original, unaltered stories.
