Who: Angel Matos
Olympics: Beijing 2008

In the 2008 Games, Matos took an injury timeout; the referee determined that he took too much time and disqualified him. Matos was none too happy and decided to prove he was still able to fight. So he did the only logical thing and kicked the ref right in the dome. The 2000 Olympic gold medalist earned himself a lifetime ban from the World Taekwondo Federation. Take a look at the initials of the Federation. WTF. Couldn't have said it any better ourselves.
