Thats because the camera isn't on him and he probably doesn't even know he's being recorded. He is also probably talking to someone that he considers a friend.
Rauno has a point, but I don't think that he's boasting to an audience. I could be wrong but I think he's just talking with a bud and stating what he feels, without knowing that he's being recorded.
Shows you how different he acts when there isn't a camera and a microphone shoved into his face. Surprisingly well spoken and a fair assessment from Nick.
Thanks for the vid.
