He's trying to be serious but he can't stop laughing so funny. I think he's laughing at the guy doing the interview or someone on the sidelines is making him laugh. Once he starts laughing he can't stop. He remind me of my best friend. She is the same way once she start laughing she can't stop. Then she makes me laugh because her laughter is so contagious just like MJ. He has such a great laugh.
