Facebook’s origin story has been told nearly as many times as Batman’s, but somehow, this cute little anecdote didn’t make it into the dozens of books written about the company. Nor was it in the Aaron Sorkin film about Facebook, The Social Network. Zuckerberg, who had spoken thousands of times before about how and why he created Facebook, had never once seen fit to divulge this secret. Imagine the amount of megalomaniacal narcissism it would take tell such an obvious lie without fear of repercussions.
