"What were they thinking?" Yes, that's a phrase one hears often if you work in the toy industry. But you also hear, "Crazier things have worked!" The fact of the matter is that both are true.

Here's a bunch of wild ideas that either made millions or got people talking. Many of them are featured in my new book, "TOY TIME!: From Hula Hoops to He-Man to Hungry Hungry Hippos--A Look Back at the Most-Beloved Toys of Decades Past," on sale now from Three Rivers Press.
