Jack: The True Story

                         "The stories are wrong of course.  It did all start with me selling a cow.  And it did end with a giant dying.  But that's just about all they got right."
                         This is the beginning of a story about a man named Jack, the same Jack that turns up in all the stories.  But he's here to set the record straight, because whoever circulated the stories (possibly that singing harp he's accused of stealing) mucked them up something awful.
                         What exactly did happen?  I don't know.  He hasn't told me yet.
