* ActorAllusion: Gary Cole wears his ring from ''Series/{{Crusade}}''; presumably it's a class ring here.
* TheDanza: Jennifer Aniston's character is named Joanna. Joanna also happens to be Aniston's middle name in real life.
* {{Defictionalization}}: ACCO had stopped making [[TheRedStapler red staplers]] years before the movie came out, but after they suddenly had a high demand for a [[http://www.thinkgeek.com/product/61b7/ Swingline 747 model stapler in Rio Red,]] they changed their minds.
* HeyItsThatGuy: Those with keen eyes will recognize one of the Bobs as [[Series/{{Scrubs}} Dr. Cox]].
** The other one was the most prominent of the minor barflies on Cheers.
** And Peter's grandfather must have fought in WW2 as a [[Series/BandOfBrothers paratrooper]].
** [[Series/{{NewsRadio}} Jimmy James]] apparently moonlights at Initech.
* HeyItsThatVoice: Bill Lumbergh? ''[[WesternAnimation/HarveyBirdmanAttorneyAtLaw He'll take the case!]]''
* PropRecycling: If it were possible to see his ring more closely, you'd find that Bill Lumbergh graduated from [[Series/{{Crusade}} Earthforce Academy]].
* StarMakingRole: Milton was the character who made people take notice of Creator/StephenRoot.
* TechnologyMarchesOn: The floppy disk that Peter and Co. use to load the virus.
* TropeNamer: TheRedStapler for the situation where a movie affects or creates a RealLife demand for an object, good or service. Swingline didn't make them when the movie was produced, but does now.
* VindicatedByCable: One of the premier examples. The movie pulled in mediocre box office numbers, despite relatively good reviews from critics, but found a second life on premium cable and on home video. [[ComedyCentral Comedy Central's]] frequent airings brought the movie to an even wider audience, quickly granting it CultClassic status.
* WhatCouldHaveBeen: After the first film's success on video and becoming a CultClassic, Mike Judge was offered the opportunity to make a sequel to the film. But making the first film was such an unpleasant experience for him that he declined.
** [[http://www.dailyscript.com/scripts/office-early-reduced.pdf This]] early script contains a lots of differences, from Initech being named Nycor, Peter losing his temper a lot, Anne disliking Lawrence, and working at Unitrode (in the final film it's called Initrode and referred to a couple times), Joanna being named Jennifer (likely they had to change it to avoid a case of TheDanza), and more.
