Mick, from Dublin, appeared on 'Who Wants To Be A Millionaire' and towards the end of the program had already won 500,000 pounds.

You've done very well so far,' said, Chris Tarrant, the show's presenter,'but for a million pounds you've only got one lifeline left - phone a friend. Everything is riding on this question......will you go for it?'
'Sure,' said Mick. 'I'll have a go!'

'Which of the following birds does NOT build its own nest?'
A: Sparrow

B: Thrush

C: Magpie

D: Cuckoo

I haven't got a clue,' said Mick, 'so I'll use me last lifeline and phone me friend Paddy back home in Dublin'.
Mick called up his mate, and told him the circumstances and repeated the question to him.

'Fookin hell, Mick!' cried Paddy. 'Dat's simple......it's a cuckoo.'
'Are you sure?'
'I'm fookin sure.' Mick hung up the phone and told Chris, 'I'll go wit
Cuckoo as me answer.' 'Is that your final answer?' asked Chris 'Dat it is, Sir.'

There was a long - long pause, then the presenter screamed, 'Cuckoo is the correct answer! Mick, you've won 1 million pounds!'
The next night, Mick invited Paddy to their local pub to buy him a drink.
'Tell me, Paddy? How in Heaven's name did you know it was DA Cuckoo that doesn't build it's own nest?
'Because he lives in a Fookin clock!'
