Dwight currently has four bobble-heads on his desk. They are of himself - a present from Angela in season two - Red BArons catcher Mike Lieberthal, retired Philadelphia Phillie Baseball star John Kruk, and former Syracuse University guard and Scranton native son Gerry McNamara.
--------------------
Dwight has a "Froggy 101" bumper sticker on the filing cabinet next to his desk. Froggy 101 is the #1 rated country-western station in Scranton, Pennsylvania, the setting for the show. This bumper sticker can also be seen in the office of Michael's boss at his short-lived night job at the telemarketing company.
--------------------
The exterior shot of the building the office is "in" in Scranton, Pennsylvania is across the street from a bar which is coincidentally named "The Office". Greg Daniels has said that he hopes this is a sign of good karma for the show. The Office (the bar) was actually condemned by the city a few years back.
--------------------
The first season was filmed in actual office space located just above a sound-stage. The sound-stage is often used to replicate the Dunder-Mifflin warehouse, most notably in the "Basketball" episode. For the second season, an exact set replica of the original office was built on a sound-stage for further shooting.
--------------------
Michael has a Union Jack Flag on his desk that appears in various shots as a homage to the original British series.
--------------------
The computers on the Dunder-Mifflin office set are wired for the internet. Cast members have admitted that when they're in the background of scenes they are often checking email and surfing the net.
--------------------
The Office's address is 1725 Slough Road, an entirely fictitious address named after the town in which the original version of the show takes place.
--------------------
Many main and supporting cast members have written episodes of the show. B.J. Novak (Ryan), Paul Lieberstein (Toby) and Mindy Kaling (Kelly) wrote 12 of the 28 episodes over the first and second seasons. Steve Carell has written two episodes so far: "Casino Night" and "Survivor Man". One episode (2.8, "Performance Review") was written by Larry Wilmore, who plays Mr. Brown, the diversity instructor.
--------------------
Four of the main cast members are all originally from Massachusetts: Steve Carell (Michael Scott), John Krasinski (Jim Halpert), B.J. Novak (Ryan Howard) & Mindy Kaling (Kelly Kapoor). Guest star Nancy Walls (Carol Stills), Steve Carell's real-life wife, is also from Massachusetts.
--------------------
John Krasinski and B.J. Novak went to high school together - Newton South High School in Newton, MA to be exact - and they both graduated in 1997.
--------------------
Some of the video used in the opening theme song specifically the exterior shot of the building was taken by John Krasinski and his friends in their Jeep. John had just got the part and was coming out for shooting.
--------------------
The cast is frequently seen on-screen drinking cans of Crystal Club soda (various flavors, Jim seems to prefer their cola), which is made in Scranton by the Crystal Club Soda Water Company.
--------------------
Poor Richards Pub, a bar the gang often refers to in the show, is an actual bar in South Scranton. It is actually in a bowling alley, South Side Lanes.
--------------------
Steve Carell only watched a few minutes of the British version before permanently stopping such viewing because he did not want to copy Ricky Gervais' performance as the office manager. John Krasinski, on the other hand, was an avid viewer of the original.
--------------------
The document being highlighted in the opening credits scene is a copy of the Los Angeles Municipal Code, Section 12.22.
--------------------
The show had to stop production in November 2007 because of a writer's strike. The show's star Steve Carell (himself a WGA member) supported the writers, and refused to cross the picket lines even for non-writing duties. Carell went so far as to call in sick to the network on the first day of the strike, citing a case of "enlarged balls" as the reason he couldn't come in.
