Tom Logan and his three friends reached the conclusion as they shared prize money of £22 after a quiz in a grotty pub that took three hours to drive to at their own expense.
Logan said: “At first I was pleased to have secured victory by knowing that Bucks Fizz’s rarely-listened-to final album was called I Hear Talk.
“But then a voice in my head said ‘Was this really worth the six solid months of your life you spent memorising 80s pop trivia in the basement of your mum’s house?’.
“I could have travelled the world, set up my own business – anything. But instead I devoted my life to learning by heart which countries border the Caspian Sea.”
