Leslie Smith fought on the prelims of tonight's UFC card in Mexico, and she is inhumanly tough. After a shot from contender Jessica Eye came damn close to entirely shearing her ear off, referee Herb Dean immediately called in the ringside doctors, who called the fight off only to be met with vigorous protests from Smith, who was definitely ready to keep going.

On the other end of the spectrum, featherweight Humberto Brown appears to have shit himself before getting choked out. Say what you will about MMA, the sport captures the full diversity of the human experience.
