Apparently they’ve had this out for a long time, but I never noticed it until now. The American Family Association markets a product called TVGuardian, which filters out any naughty words that might otherwise fall on your precious child’s virgin ears. And boy does it work!
Of course, that will depend on the setting one chooses:
I think it’s quite amusing that you can be so strict as to filter out hell and damn. Then they could watch Christian TV and not have any idea what they’re talking about. It would be even funnier to have it replace curse words with their clean alternatives, like “fudge” for fuck or “sugar” for shit. Especially if it did so in a Stephen Hawking-style electronic voice.
