Who can forget the bare-chested photo of former New York Congressman Anthony Weiner? First, he denied tweeting it to a young woman. Then, came his confession.
President Bill Clinton told the nation a whopper of a lie about intern Monica Lewinsky, saying, "I did not have sexual relations with that woman, Miss Lewinsky." Then came his confession.

He later fessed up during a 2009 ESPN interview.
