I'm now to the point where I'm turning the TV off when certain commercials come on because I hate them so much. The latest one to irritate me is one where some idiot guy is looking at a motorcycle, then a woman comes up and he tries to impress her by saying the motocycle is his. Of course, it's not, and when the real owner arrives and rides away I get so annoyed that I want to throw something at the TV. I'm not really sure why it annoys me so much, but I can't stand seeing the ad.
This is the reason that I generally don't watch TV at all, I think. I get so frustrated at the lack of creativity in the commercials, as well as the inability of commercials to stand up to repeat viewings, that I hate to have the TV on at all.
