Who are the dumbest poker professionals?

I saw Laak openly verbalizing several of his decisions in front of Chan while heads up last year at WSOP. Ok, it wasn't an earth shattering discourse but nonetheless, I still haven't figured out what part of verbalizing his decision in front of the 9(now ten) time world champion he thought would help him. Um, I'm going to cover my face but tell you what i'm thinking.
