The French legend and Marco Materazzi exchanged words throughout the match, but then Zidane casually jogged in front of the Italian defender and unleashed the Headbutt Heard 'Round the World. After launching his skull into Materazzi's chest, knocking the Italian to the ground, Zidane -- who was also playing in his final game -- received a red card in the waning minutes of the second overtime. The Azzurri went on to win 5-3 on penalty kicks.
