Nyle's martial arts face

Today in martial arts, Nyle's face was priceless.  They took turns breaking boards by either kicking or punching.  He chose punching.  After punching through the board he turns to me with a completely serious stare that seemed to "I am so dang tough...did you see that...I don't even have to say a thing."  He continued the stare during his entire strut back to the back of the line.  All of the parents were dying.  He did it both times.  Even his walk was tough.
