It's such a civilized game. The biter in question is reportedly Uruguay's Luis Suarez.

The incident, shown on television replays, showed Suarez apparently bite the shoulder of Italy defender Giorgio Chiellini as the pair clashed in the Italian penalty area. It happened about a minute before Uruguay scored in the 81st.

And thank God Twitter now hosts GIFs (or GIF-like things, at least).

UPDATE 12:28 PM: Wow, this Suarez guy is a real piece of work. He's already faced punishment for "racially abusing" a player on Manchester United, and he's also had two other biting incidents.
