Who Knew? is a collection of tidbits and trivia about well-known personalities and products that we all are familiar with - or at least think we're familiar with. For example, did you know that the VW Beetle was commissioned by Adolph Hitler (and designed by Ferdinand Porsche)? Or that the name "Oz" came to author L. Frank Baum when he noticed the drawers of his filing cabinet were marked A - G, H - N, and O - Z? From Twinkies to Tupperware to toys and television, these offbeat informational nuggets are guaranteed to entertain and enthrall.
