It's not so much one Doofus as a whole collection of Doofi today! Wendy Roby has just published a book in England called 'Universally Challenged'. It's described as follows:
There's nothing quite like a quick fire question, the pressure of a countdown, or the expectant stare of Jeremy Paxman for making even the most intelligent quiz show contestants (as well as the not so clever) come out with the most unbelievably stupid answers. "Universally Challenged" is a collection of slip-ups, blunders and misunderstandings from contestants who really are the weakest link.
The Daily Mail has published an article citing many of the funnier question-and-answer exchanges in the book. Here are a few to whet your appetite (and start you laughing!).
