Stromberg is a German mockumentary comedy series that first aired in 2004, following insurance office manager Bernd Stromberg, played by Christoph Maria Herbst. Modelled in style on workplace documentaries, the show built its humour around Stromberg's awkward confidence and blunt one liners. Short lines like doch, ist klar became easy to lift as reaction clips because they need no setup and keep his voice in a single beat. Fans still share them online as shorthand for a smug, sarcastic yes in everyday conversations.
