Oh, there are so many...fortunately, with the advent of the DVR (aka TIVO), we never watch TV in real time any more except for sports, so we usually just fast forward through the commercials. However. The one I hate the most right now because it just creeps me out is the Cadillac commercial that ends with the line, "When you turn your car on, does it return the favor?" GAH. Ick. And there are 2 versions, one with a guy saying it and one with a girl, and I have to say, the one with the guy is WAY creepier - he manages to deliver that line a way that makes him sound like a pedophile.
