Well, he talks like that all the time so I doubt it's completely put on. He has a dry sense of humour at times which I like, maybe those are the times you don't get it? TB has also said time and time again that he doesn't have as much knowledge as other casters and shuts up whenever someone with more knowledge is analysing the game. He is a shoutcaster and does a very good job at keeping the game active when there's nothing much going on. I like him and I think he does quite a good job. He needs to lose that hat though... It's just silly.
