Hogan bamboozles Burkhalter and Klink into believing that Carter's rabbit trap is a "Gonculator": a top secret contraption that will help Germany win the war. Classic HH episode!
It even made it into Webster's online dictionary of computing: "(From "Hogan's Heroes", the TV series) A pretentious piece of equipment that actually serves no useful purpose. Usually used to describe one's least favourite piece of computer hardware." 😂
