Taekwondo as with any martial arts is a very hard thing to master, and as we all know sometimes things do not go as planned.

This poor guy is doing one heck of a demonstration as these boards must all be made out of cement. I also wonder how much he had to pay the one guy to hold the block of wood, who continually gets punched or kicked in the hand.

Hopefully for some of the parents that have kids enrolled in his class, they can get their money back!
