Cuckoo?

A contestant on "Who Wants to be a Millionaire?" had reached the final plateau. If she answered the next question correctly, she would win $1,000,000.If she answered incorrectly, she would pocket only the $32,000 milestone money. And, as she suspected, the million-dollar question was no pushover.Which of the following species of birds does not build its own nest but instead lays its eggs in the nests of other birds?
A The condor
B. The buzzard
C. The cuckoo
D. The vulture
The woman was on the spot. She did not know the answer. To make matters worse, she had used up her 50/50 Lifeline and her Audience Poll Lifeline. All that remained was her Phone-a-Friend Lifeline, and the woman had hoped against hope that she would not have touse it, mainly because the only friend that she knew would be home happened to be a blonde. But she had no alternative.She called her friend and gave her the question and the four choices.The blonde responded unhesitatingly: "That's easy. Theanswer is C: The cuckoo."The contestant had to make a decision and make it fast. She considered employing a reverse strategy and giving Regis any answer except the one that her friend had given her. Considering that her friend was a blonde that would seem to be the logical thing to do. On the other hand - the blonde had responded with such confidence, such certitude, that the contestant could not help but be persuaded."I need an answer," said Regis. Crossing her fingers, the contestant said, "C: The cuckoo.""Is that your final answer?" asked Regis."Yes, that is my final answer."Two minutes later, Regis said , "I regret to inform you that that answer is... absolutely correct. You are now a millionaire!"Three days later, the contestant hosted a party for herfamily and friends - including the blonde who had helped her win the million dollars."Jenny, I just do not know how to thank you," said thecontestant."Because you knew the answer to that final question, I am now a millionaire. It was the assuredness with which you answered thequestion that convinced me to go with your choice. By the way... how did you happen to know the right answer?""Oh, come on," said the blonde, "Everybody knows that cuckoos don't build nests. They live in clocks."
