A couple months into my first job, the chief engineer, who was an ME in an EE company, told me to figure out how a certain filter worked. I sat down at my desk with the diagram for hours struggling with it. Then I got up to go to the bathroom or something and came back in through a different door and saw the schematic upside down and that from that perspective it looked totally different. It was just a 2-port network; I know all about 2-port networks!

A few minutes later I was done :-)
