You probably think of him as a fat guy in a big red suit, but you'd be surprised at how much you don't know about both the real St. Nick and his traditional legend. For example, his red suit was only standardized in 1931, thanks to an ad campaign by Coca Cola.
According to legend, he fought to save young women from prostitution, fought off a cannibalistic butcher and even spoke immediately after being born, exclaiming, "God be glorified." Find out more about Old St. Nick over at io9.
