Scott Wiener loves pizza.

By day, he leads pizza tours around New York City.

By night, he shares his Brooklyn apartment with his world record-holding pizza box collection. (Well technically, a few of the more than 1,400 boxes are at his parents' house.)

Scott calls himself a pizza enthusiast, but let’s face it -- he’s obsessed.

He’s visited tomato farms in California and buffalo farms in Italy, to see the see pizza's key ingredients at the source. He’s scoured old phone books and marriage records to learn when certain pizzerias opened and who owned them.

He’s even planned entire vacations around visits to pizza box factories.

"Whenever I go anywhere, my first thought is, oh what are the pizzerias nearby that I've been meaning to check out."

This week on The Sporkful, Scott schools us in the history of pizza -- from its humble invention to its unlikely rise to culinary fame and fortune.

And we learn how his pizza obsession affects day-to-day life ... from finding an apartment big enough for all those pizza boxes ... to dating:

"It's very much truly me. So if I'm getting to know someone, they will need to know this at some point. But maybe not in the first five minutes."

Plus, Dan and Scott go out for slices and discover the one thing about pizza that divides them. Listen in to the episode for that argument!
