"That's okay bud, I can do the math part of my Chemistry homework all by myself, but maybe I'll let you help me study for my Anatomy class. I am going to have to know all the bones in the body and there are hundreds". Motormouth as been working on making a three dimensional skeleton constructed completely of white paper and tape. Why? Who knows, this is what the kid does for fun. "Hundreds of bones?"
