It's fun and easy.
All you need do is visit Donald Wildmon's website at
http://www.afa.net and click on the first "complaint" link.
Check this shit out: Last Sunday, the Eagles were playing football and Fox was carrying the game. One of the camera operators, apparently one who doesn't like the Eagles very much, found a woman in the stands wearing a t-shirt that says "Fuck Da Eagles" on it and focused on her for a few seconds. One of the engineers, also apparently one who doesn't like the Eagles either, put it on the air.
Now the American Family Association's all up in arms and trying to get its followers to write to the FCC to complain.
I wouldn't normally tell anyone to support one of Wildmon's causes...but fuck it, man, it's Fox! I like them even less than I like Wildmon.
