If you saw the Clinton clips before hand something was very apparent - Clinton bashed others, not himself. AP did a clip of past presidents. For the republican ones they had comedians mocking them. When they got to Clinton they had Clinton up there making his own jokes, about others. They did have Reagan at the end make a good one. (tagline).
Point is, Clinton's so full of himself he uses even this dinner to brag about his "accomplishments" and can't even bring himself to be humble. And the press loves him so much, they play right along.
Good point! I was thinking how Clinton felt obligated to control the event. He looked angry at having to be self deprecating
