Scott Wiener, the man who runs Scott's Pizza Tours, is not just an expert on New York slices, but on all things pizza. His obsession with the food grew as he traveled the country, cataloging every bite he tasted in his online Pizza Journal. For fun, he would drive his friends around New York's boroughs in search of new pizzerias.

Finally, one of his buddies suggested he do it for a living. Now he enjoys press from around the world as a sought after pizza expert; he even became a tasting judge at Pizza Today magazine's International Pizza Expo.

In Asylum New York's new video series "Space Invaders," correspondent Ryan McKee crashes Wiener's apartment and learns just how deep his pizza passion runs. The Brooklynite's collection of pizza boxes, accessories, novelties and literature is so impressive, it's damn near pathological.
