Your pics, and the article simply reinforce my thoughts about this.
Hey 0Dumbo, I have a finger for ya and it is not my ring finger you POS liar.
I remember Clinton. He was a pretty good liar. Sometimes he even seemed to enjoy lying. But when someone -- reporters, political opponents, whoever -- forced him (as he saw it) into lying, he would get really, really angry about it. (Remember how that bony finger would come out.) Clinton wanted to lie on his own terms.
Obama seems similar. Like Clinton, he fully expects everyone to accept his lies, not only without reservation, but with gratitude. He doesn't like being disbelieved. And, like Clinton, the bigger the lie the angrier (and the more self-righteously angry) it makes him.
This is, of course, opposite the behavior of psychological normal persons, who are embarrassed and discomforted, i.e. shamed, as opposed to morally outraged, when they are "cornered" into telling a lie, or when they fail in selling an unpressed lie.
