It was an episode of the immensely popular TV show - 'Million Pound Drop' of a UK Channel 4. The husband-wife team of Johnny and Dee had to leave the show with a prize money of $518,000 when they had been aspiring for the $1 million prize money. They apparently gave an answer that was not the correct one as per the documents held by the host of the show. The question was - 'who played Dr. who the longest time'. However, when fans rang up to the channel and pointed out the error, the TV show hastily apologized and have asked the contestants to join from where they had left off - and try to complete the game and bag the prize.
