Scranton references can come from the most unlikely of places...even Playboy Magazine.
The May 2011 issue of Playboy (Karina Smirnoff cover) features a 20 Question interview with actor Ed Helms (Andy Bernard on The Office, and star of the upcoming The Hangover II) written by Eric Spitznagel (pp. 86-87; 116-119). Check out question 12 (page 188) below, in which Helms discusses one of his experiences at The Office Convention in Scranton in 2008:
A few years ago, you attended an Office convention in Scranton, Pennsylvania, where your fictional Dunder Mifflin paper company office is located. What are the hardcore fans really like?
They're pretty extreme, man. At that convention we were like The Beatles for a weekend. We had a police escort just to get around town, and everywhere we went there was a round of applause. At one point I was in a car with [Office co-star] Angela Kinsey in downtown Scranton, and we passed a model-train store. I asked the driver to stop so we could go in. And before we knew it, fans were starting to pour in. A cop eventually showed up and said, "Everyone out." And they shut down this store so Angela and I could walk around and look at model trains. That was just crazy to me. I thought that shit only happened to Justin Bieber.
