Funny things Kid do?

My son who will be 2 in september has learned to say HIYA like a karate person would say when kicking some butt. So my son finds whatever he can and uses it like a weapon and says HIYA all the time. But the funny part is the stances he does or how he places his body and moves his body when he is pretending to well i am not even sure what he is pretending to do but he just looks so silly wiggling around and say HIYA that you cant stop laughing most times.
