Paddy has entered Who Wants To Be A Millionaire and finds himself by some miracle through to the last question.
"Now Paddy," says the presenter, "for the top prize, can you tell me which of the following birds do not build their own nests, the thrush, the blackbird, the cuckoo or the wren?"
There's a lot of money riding on this and Paddy is sweating. He decides to use his last lifeline which is to Phone a Friend, calls up his mate Mick and repeats the question. "Easy," says Mick. "It's the cuckoo." Paddy gives that as his answer and walks away with the top prize.
Back in his village, he's celebrating with his friend Mick and asks him how he was so confident about the answer to the question.
"Easy, ya eejit!." says Mick. "I thought everybody knew cuckoos live in clocks."
