Haven't had cable TV for at least 10 years now and I can't stand watching most shows at other people's houses who still sit through all the car/truck, pill and insurance commercials. I literally feel dumber having watched a few in a row. I really believe there is a science to be discovered there, like slight or temporary brain damage occurring because of commercials. They're so fake/plastic and I feel like I'm being manipulated through some kind of meme the advertiser is trying to push through repetition instead of on the product's merit.

Edit: What I mean is, nobody acts in real life like they do in commercials. I feel dumber watching people behave that way. I get it's supposed to be persuasive but something about modern commercials just irks me to no end.
