I sort of knew a dude who accidentally started a mens rights group in college (as in we knew each other's names and had a class or two together).
He wrote a satire column in the school paper poking fun of the Women In Business student group about a new group he would call Men In Power
Of course there was some outcry...then there was some national news pickup (that missed that it was a joke) so the guy just decided to run with it and take the TV interviews and national newspaper articles. I think he got it turned into a registered student organization with funding and everything (renamed to "Men Initiating Progress") although I doubt it still exists today.
Edit: according to facebook, he just passed the bar. Good for him.
