What about Bob?

To our surprise, our little Matt gave himself a nickname. He goes by the name "Bob" at school. I guess everyone at school - students and teachers - call him Bob now. He's become quite the joker, constantly trying to be funny. Fortunately (or unfortunately I'm not sure which yet), most of his attempts are met with smiles at the very least. How can you not smile when he looks at you like this? He drank some chocolate milk the other day, and what appeared? The perfect joker smile.
