It’s no secret that Larry Flynt, the often-controversial founder and publisher of Hustler magazine, is not a fan of Mitt Romney. (Maybe that’s because the Republican nominee has said that he supports federal obscenity laws—which aren't exactly good for Flynt’s business.) It’s also no secret that Romney opponents have been dying to get their hands on his unreleased tax returns, which, they claim, could prove that the candidate hasn't been paying his fair share of taxes. Now, Flynt is joining their cause by offering a $1 million reward for Romney's tax information.

Flynt is taking out full-page ads in this Sunday’s edition of The Washington Post and Tuesday’s USA Today that promises “up to $1 million” for the dirt on Romney’s “unreleased tax returns and/or details of his offshore assets, bank accounts and business partnerships.” (But before you go calling the Hustler hotline, be aware that Flynt will need “documented evidence of your claims.”)

According to the ad, all correspondence will be kept confidential—so if you’re a former Bain exec with a bone to pick (or without a golden parachute), you might want to get a pen.
