Just finally watched it, I couldn't bring myself to do it before as I really think this tactic is counterproductive. I only read a couple of pages when it first came up, so if I'm repeating someone else's comments please excuse me.
After watching it, and listening to Tony's reactions, I tried to imagine what it was like for him to take a call like this. I'm sure he lives in a bubble surrounded by yes men much like any celebrity. But I wonder what went through his mind after hanging up. Is he so sure of himself that the conversation wouldn't make him stop and think, especially considering his reaction to the beginning about the tight pants? I bet he's heard comments about that from his peers.
In my experience, men with positions in the organization put on an air of humility until questioned, and then you see what they really are. Maybe this made more of an impact than you think. Or maybe it just cemented his ideas further in his deluded mind.
