It had stumped listeners for weeks but Spin 103.8's 'Big Question' was finally discovered earning a Dublin woman a cool €4,000.
Tracy Clifford and Ryan Phillips, hosts of the Fully Charged morning show, had given listeners the answer 'blue' weeks ago and were giving cash to the lucky person who could guess the answer.
Leanne Macken from Donaghmede beat off all the competition when she correctly guessed that the question was: 'What colour is Leonardo's mask from The Teenage Mutant Ninja Turtles?'.
It is the biggest cash prize ever given out on the stations morning show and continues tomorrow.
