Hey, remember that couple that lost it all on the first episode of The Million Dollar Money Drop? They had the right answer but the show didn't know it and ruled them wrong.
Since they blew the last, "all or nothing" question, they probably would have gone home with bupkis anyway but due to outrage on the Internet, the producers have announced they'll have that couple back to play again. This is not only fairness, it's just Good Television. On a show like that, you want contestants for whom the audience will root. Aren't you more inclined to root for that couple than for someone new?
Mark Thorson, who reads this site and sends me invaluable typo corrections, sent me the link. He asks, "…how can that happen unless they film some new shows?" Answer: The producer is assuming there will be more shows. Perhaps they already have a network order.
