A Non-Smoker's V-Chip?

I wish there were some way I could explain to my T.V. that I'm not a smoker because I'm getting pretty tired of the escalating grossness of anti-smoking ads.

The most recent offender is an ad in which they snake a video camera down into the lungs of someone with lung cancer, giving us the viewer an up close and personal look at the patient's tumors.

Thanks. I'm trying to enjoy a football game with my friends and now I'm about to hurl into the spinach and avocado dip.

But I'm not, and never have been, a smoker, and I'd like to not put up with this public service overkill. So I'm going to invent a non-smoker's V-chip I can install in my T.V. so when these ads come on I'll get instead ads for Doritos, or beer, or something else that can kill me legally.
