In boxing, they say the first rule is to protect yourself at all times. We think this rule should also apply to mixed martial arts. Because your opponent wants to destroy your face and will absolutely do so if you give him a free chance.

However, Joe Harding apparently never learned that rule. In Harding's recent fight against Johan Sega, Harding made a bad, bad mistake by showboating in the middle of the round -- and he got a devastating knockout kick to the face as his punishment.

It's a lesson he won't forget -- that is, if he can remember it ever happening.
