On November 21, Fox Broadcasting Co.'s long-running hit animated show The Simpsons took a pointed swipe at Fox News offering up “Not Racist, But #1 With Racists” as an alternative slogan for the self-branded “Fair and Balanced” cable network:

O'REILLY: Continuing to bite the hand that feeds part of it, Fox Broadcasting once again allows its cartoon characters to run wild.

The Simpsons was right back to needling Fox News on Sunday's show in which the right-wing network was given yet another alternative slogan, this one reading “Unsuitable For Viewers Under 75.” Here's a still from last night's show:
