Isn't it captivating to stop in mid-sentence? I'm reminded of an old Gossage ad where he ended the full page long copy ad in the middle of a sentence and continued it the following week (that man was a genius). This brings me back to my friend. His ad had a complete resolution at the end. There was nothing left to think about. There were actually 2 full anti-climaxes to the ad.

why would anyone keep thinking about an ad if there's nothing left to think about?
