Chris tarrant: "Laura, you've done very well so far - £500,000 and one lifeline left. The next question will give you the million pounds if you get it right ... but if you get it wrong you will drop back to £25,000 -- are you ready?"

Laura: "Sure I'll have a go."

Tarrant: "Which of the following birds does not build it's own nest? Is it...

A-Robin
B-Sparrow
C-Cuckoo
D-Thrush

"Remember, Laura, it's worth 1 million pounds."

Laura: "It's a cuckoo."

Tarrant: "You're sure? You can walk with the £500,000 or play on for the million."

Laura: "I want to play, I'll go with C - Cuckoo."

Tarrant: "Is that your final answer?"

Laura: "It is."

Tarrant: "Are you confident?"

Laura: "Absolutely!"

Tarrant: "Laura.....you had £500,000 and you said C -Cuckoo. Well....you're right! - You have just won ONE MILLION POUNDS Here is your cheque. You have been a great contestant and a real gambler. Audience please put your hands together for Laura."

That night Laura calls her friend Jim and they go to a local bar for a celebration drink. As they are sipping their champagne. Jim turns to Laura and asks, "Tell me, how did you know that it was the cuckoo that does not build its own nest?"

"It was so simple," Laura replied, "Everybody knows that cuckoos live in clocks."
