This is nothing new. We have seen his temper in action before. Did he really think that "therapy all day" and "sleeping on the couch" (in the White House, yes, we certainly all believe that... They had separate bedrooms, anyway!) stuff was going to fool us? Lewinsky was not his only affair inthe White House! He was NEVER penitent, just upset that he was caught.
This is the real Bill, all right.
And as I recall, the first time we saw him angry about "Miss Lewinsky" was when he blew a fuse at US, the American People, and shook his finger in all of our faces and told us he had had no "relations."
