The US Office (or just The Office as it's known to those in and around Scranton, Pennsylvania) is regarded as one of the true gems of television comedy. Not merely an Atlantic transplant of the UK series, the American sister show became a creature of its own, creating new and lovable characters that allowed it to differentiate itself from the Ricky Gervais and Stephen Merchant creation.
For a show that spanned nine seasons, there are tons of bloopers, gags, out-takes, additional material (with the writers often having enough material for almost double the episode length) and trivia facts that exist in the show that can be appreciated by fans and non-fans alike.
For instance, during the filming of the episode where Michael seeks to find a suitable replacement for his job entitled "Beach Games", Rainn Wilson (Dwight) accidentally kicked sand into the eye of Leslie David Baker (Stanley), with Baker needing to go the local emergency room to have his eye washed out.
The show is littered with minute nuggets of trivia, like Charles Miner's previous employer Saticoy Steel named after Saticoy where the show is filmed in LA and Danny Cordray (Tim Olyphant) named after producer Randy Cordray. All these little facts hiding in one of the champions of American television comedy.
