More than 20 years ago, The Office hit TV screens in the UK. It was headed up by Ricky Gervais, and specialised in dry, British humour and an eccentric boss.
Just four years later, The Office US made its debut. It went on to become one of the most iconic and successful sitcoms of all time, with many of the stars rocketing to Hollywood fame as a result.
Whether you prefer the original, or think the US version is better, you have to admit that The Office is hilarious - and only gets funnier every time you re-watch it. With nine seasons, and 201 episodes, The Office US is full of trivia and jokes only true fans will remember.
