In an homage to The Da Vinci Code (2006), in season nine of The Office in episode twelve “Customer Loyalty”, Jim Halpert uses a mid-1950s Royal Quiet De Luxe typewriter to forge a letter from Robert Dunder which sends Dwight Schrute on a faux quest for the holy grail in what Jim calls “The Dunder Code”.
That’s so cool! I just got this typewriter recently (although without the cool green keys). I had no idea.
