Hulk Smash!!!

So for awhile now J has done this thing where he makes hands into fists and tenses up his face.  He has done it when playing, when he is mad and just at random times. So today at lunch he did it and Brian asked him if he was "Hulk Smash"!!!  So J did it again and again.  So now something that he would do when kinda having a fit has now become funny and playful.  We were at Best Buy today and J was riding in the cart and Brian got him to do it again and I caught it on video. Pretty fun.
