Here is a nice story realy happend in german tv, sorry for my bad english.
In the german quiz-show "Wer wird MillionÃ¤r" (Who becomes a millionaire) from January, 31 2003 the 8000-Euro question was: Every rectangle is: (a) a rhombus (b) a square (c) a trapezoid (d) a parallelogram.
In this show _allways_ exactly one answer is (has to be) correct. The candidate was so confused, she didn't know if c or d is thw right answer, so she skipped the question and went home (with "just" 4000 Euro). In the following days the broadcast station got tons of mails, letters and phone calls. Nearly all "mathematicians" regarded c _and_ d as correct. The broadcast station told, that they looked up in three different encyclopaedias, all three saying that trapezoids have only one pair of parallel sides. Taking this definition only d is correct.
That's the problem. Who is right: More than 90 percent of the mathematicians saying a parallelogram is also an trapezoid or three encyclopeadias saying the opposite?
The Solomonian solution. In the next week the candidate got a "new" 8000-Euro-question.
