Smiley Bob realizes that he's not the most attractive man out there and that the world isn't perfect. He even knows that although I would have done a better job with my right hand, he was created with my left. This is what makes him look like he has shards of glass sticking out of his face. It doesn't phase him. He smiles. He knows from psychology lessons that a smile acts physiologically to make the mind believe in happiness. Take his example. Smile.
