Scott Weiner holds the Guinness World Record for the Largest Collection of Pizza Boxes. Weiner, who owns a pizza touring company in New York City, has become an expert in pizza boxes. Today's boxes hold more than just pizza — they're an extension of the pizzerias themselves. In this episode of the Pizza Marketplace Podcast, Pizza Marketplace Editor Mandy Detwiler talks to Weiner about his collection -- which she personally certified by counting his collection twice. He's got nearly 1,900 pizza boxes now, and his collection has grown out of his Brooklyn apartment to a storage unit.
