This karate kid may need more practice waxing on and waxing off.

The little boy in this clip successfully breaks a piece of wood and calmly walks back to stand with his fellow karate students where he only then makes a face to show the agonizing pain he feels.

Kudos to him for maintaining the proverbial game face until he's back in line and then transforming from karate killing machine to little kid dealing with debilitating pain.

Maybe he should ice his hand. We'd love to see him do it -- but only after he breaks a huge block of it all by himself. Then, he'll know what real pain is all about.
