No but I forgot about that one. It's a good one too. Thank you.
The one I remember was about a "technician" in this world where nobody remembers the underpinnings of technology. There is a big competition to solve a known problem using the existing tech toys that are available. (something like a tech olympics) The technician wins the competition by using the equipment in non-standard ways and re-engineering their functions in ways nobody had ever done.
The judges are at a loss as to how he could have done this since it is not in any instruction manual. :-)
(A technician discovers how to do simple arithmetical calculations in a world where no remembers arithmetic since its all automated away.)
