Blonde winner

A blonde named Barbara appeared on Who Wants to be a Millionaire....

Regis: "Barbara, you've done very well so far, $500,000 and one lifeline left--phone a friend. The next question will give you the first ever million dollars if you get it right.... but if you get it wrong you will drop back to $32,000...are you ready?"

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

Regis: "Which of the following birds does not build it's own nest? Is it...
A-Robin, B-Sparrow, C-Cuckoo or D-Thrush
Remember, Barbara, it's worth 1 million dollars."

Barbara: "Oh, gees, that's simple.... it's a cuckoo."

Regis: "You're sure? You can stick on $500,000 or play on for the million."

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

Regis: "Is that your final answer?"

Barbara: "It is"

Regis: "Are you confident?"

Barbara: "Absolutely"

Regis: "Barbara, you had $500,000 and you said C-Cuckoo. Well....you're right! You have just won 1 MILLION DOLLARS!!!! Here is your check. You have been a great contestant and a real gambler. Audience please put your hands together for Barbara."

That night Barbara calls her friend Carol and they go to a local bar for a celebration drink. As they are sipping champagne, Carol turns to Barbara and asks, "Tell me, how in God's name did you know that it was the cuckoo that does not build it's own nest?"

"Get real!" Barbara replies, "Everybody knows cuckoos live in clocks!"
