Japanese High School Baseball Player Makes Me Happy

I understand that this kid probably deserves a baseball to his ear for these antics at the plate given the unwritten rules of baseball, but I can't get over just how happy he is.  I'm not sure I've ever been this excited about anything in my life.  It actually makes me want to go jump around doing something I love.  Kinda the same feeling I got after this kid convinced me I could run through a wall.
