  • The first use of the word dongle that I can find is in the influential BBC radio show The Goons dating back to January 24th 1956

    In the episode The Jet Propelled NAAFI (series 6 Episode 19) the character Seagoon says

    "Great larrups of dongle. He thinks he's a little tea-stained, crumpet-ridden idiot."

    Also in December 1957. The episode Vanishing Room contains the line

    "Flip my dongle and lower my grobblers"

    The word was also used in one of the early Monty Python episodes.
