What's something really trivial, I mean utterly and completely unimportant, that just annoys the hell out of you? For me, it's teeth whitening commercials. There's this one where a chick gets invited to some fancy event over the phone and she's like "Oh..." in the mirror, rubbing her finger on her completely flawless pearlescent white teeth, as if they were brown or something, so she uses the teeth whitening product to make her teeth blue! Seriously, use somebody with [i]yellow teeth[/i] for a teeth [i]whitening[/i] commercial, not someone with flawless teeth!
