A long, long time ago I used to have a retail bookstore. At that time smaller publishers couldn't justify the expense of a salesman so they paid some goober to call and read whatever promotion they had going on. In describing one of the promotions he said, "this book is written for teenagers by a man who is an ex-teenager himself."
I pointed out that it's kinda hard to skip those years and go straight to adulthood - he acted offended. I'm guessing the ad writers decided to have fun with this socially challenged individual.
