So, my Son, wife and i are in the early stages of potty training for my 21 month old. He's sitting on his potty while my wife and i are across the room watching TV, and he starts yelling BRAIN!!, BRAIN!!, BRAIN!!!!!. So my wife and i walk over to see what the comotion is about and the boy has got his head almost completely between his knees, staring at his junk, yelling BRAIN!!!!!!. Guess the little fella learned early what "brain us guys really think with.
