As legend (or this official video) tells it, Enzo Ferrari only recounted the story of the origin of his company's famous prancing horse badge the once. So you may not have heard it.
Frankly though, we don't believe he only told it once. I mean, how could anyone possibly know that? He must have been asked the question at dinner parties every night of the week. So did he respond archly with silence and a meaningful look, or maybe with that weird 'finger pulling the lower eyelid down' thing the Italians use when they don't want to give you a straight answer? How annoying must that have been...
Oh well, it's on the internet, so it must be true.
