Cuban taekwando competitor Angel Matos takes umbrage with Chinese referee - and rebuts with a few swift kicks to the cabeza.

The video is currently here, but those nasty copyright-enforcing goons at YouTube keep removing it. Note how the French announcer no-sells the excitement like it's just another Jean Reno movie.
