I would give it to the National Enquirer for nothing, asking only that they never divulge my identity.
If I had to report income from the picture to the IRS, you can be sure that Lois Lerner (or whoever her corrupt successor may be) would see to it that I was harassed and audited every year for the rest of my life.
If there's one thing the crooked politicians won't tolerate, it is a whistleblower. That's the one unforgivable sin... everything else can be bought off.
