Well, I respect your opinion. But, if an MD or psychologist or psychiatrist is not MY doctor or my client's doctor, then I'm calling him or her Mr. Unless we happen to be located in their workplace at the time, or a patient is present.
I'd like to know why Ian is so concerned about his image, why he's so extremely pretentious. He has to be smarter than everyone else, better educated, more knowledgeable, etc. While insufferably pretending to be modest and claiming otherwise. Even his god-awful so-called jokes have to be better. If he perceives a caller (or probably anyone else) is somehow suggesting otherwise - almost always inadvertently - the true Ian comes roaring out.
No one can be funnier than him, no one can express a fact he's unfamiliar with on the subject matter, no one is allowed to bring up an angle that didn't occur to him, or question something he said - or he gets upset, dumps the call, claims the caller hung up, and then insists all he wanted was to have a conversation.
He's a fat, petty, conceited little asshole. And it's too bad because he does have talent and can do a pretty good show when he manages to stay out of his own way.
