The clip comes from the American version of The Office, the NBC workplace sitcom that ran from 2005 to 2013. Oscar Martinez, played by Oscar Nuñez, was the level headed accountant in the Scranton branch, which is why his rare moments of exasperation became so quotable. Short lines from the show spread widely as reaction clips on social media and messaging apps, and this deadpan unbelievable survived because it fits almost any frustrating announcement, bad excuse or unbelievable story shared at work.
