Without it, we never would have gotten Elvis

It's the 50th anniversary of the debut of the hula hoop, the innocent toy that sent hips a-swivelin' the world around. To think, if there was no hula hoop, Elvis might have gone on "Ed Sullivan" and thrown a frisbee or watched a bad 3-D movie. His career, to be sure, would be over, but maybe he'd still be alive today.

Think about that. Video games might be cool, but plastic changed the world.
