The boy who would be king

My 2 year old boy thinks he's a king. If I say, "Where's king so and so?" he says, "Right here," and points to himself. Ha ha. But the other day when we were reading a book about King Arthur and I said, "Look, there's King Arthur's crown," pointing to his head. "Every king has a crown," my son put his hands on top of his head while wearing a questioning look on his face and said, "Where's my crown, mama? Where's mine?"
