Million-Dollar Idea.

I'm going to write a pair of sex and relationship advice books entitled Don't Sell This Book to Men and Don't Sell This Book to Women. The advice will be entirely generic, but the aura of gimmicky secrecy, the cross-gender peeking, and the inevitable controversy (especially if some goofy bookstore manger takes the titles seriously--and I should pay one to) will make me a millionaire.
