"Men men men men, manly men men men…." is not just Two and a Half Men's obnoxious theme song. It is the theme song for LIFE, as illustrated by a new Tumblr called "100 Percent Men" that shines light on "corners of the world where women have yet to tread." (Whether we want to tread into all of these irrelevant corners is another issue.)

Those boy's clubs include the top editors and reporters at Talking Points Memo, New York comedy festival comedians, Presidents of the United States, the European Central Bank Governing Council, Shell Oil's executive committee, and many, many, manly others.
