On December 3rd, 1976, two simple words boomed from the silver screen that changed movie history forever. They have stayed with us for 40 years, all from a movie which wasn't even considered to be that significant when first being produced.
Yet forty years later, we still watch it and cheer for the main character through our imitation of him screaming those very two words. That character is Rocky Balboa and with "Yo Adrian!", Rocky became a cultural phenomenon.
