UFC welterweight champ Georges St. Pierre headed to Japan for UFC 144. He visited a school for young kids and was promptly beaten by children wielding swords.
Seriously, watch the first two and a half minutes of this video. Your day will improve. Watch as GSP beams while the children warm up, then see him not keep up as they run through exercises with plastic swords. Finally, see how they suddenly turn on him and beat GSP over the head until he submits to strikes.
