Have you just written a slogan or headline for an advertisement which doesn’t exactly get to the point? Or (more likely) has an advertising agency just proposed something really bland to you? I suspect you will really enjoy Things Real People Don’t Say About Advertising. The moral of the story: read what you’ve just written out loud to someone who doesn’t really care, and see if they understand what you’re getting at.
(note: a couple of examples on the earlier pages use expletives which might be deemed ‘not suitable for work’)
