The Long Arm of Coincidence

It was nine o'clock in the Paddington Tavern in Brisbane, and Paddy McGinty went to the bar for another refill of his XXXX. He went back to his table and sipped meditatively at the beer. A moment later, he was joined by another man, also armed with a schooner of XXXX (that's the Queensland beer, folks).
'Good night to ye,' said the newcomer. 'Daniel McGinty's me name.'
Paddy raised an eyebrow. 'McGinty? But that's my name!' he exclaimed. 'Quick -- down your beer, and I'll git ye a Guinness!'
They downed their beers, and Paddy bought two Guinnesses.
'Where are ye from?' Paddy asked.
'Oi'm from Dooblin,' said Dan.
'Would ye believe that?' asked Paddy incredulously. 'Dooblin! Why, I'm coming from Dooblin meself, I am. Went to the Sacred Heart School, I did. '
'The Sacred Heart School!' cried Dan. "Why, I went to the Sacred Heart school! That calls for another Guiness!'
So Dan went and bought two more Guinesses.
'So tell me,' said Dan, eyes alight with interest, 'When did ye leave the Sacred Heart School?'
Paddy scratched his head. 'Oi left in 1960,' he said. 'Oi lived in Martin Street, and Oi went to work wid me father at the Foundry in Kilmartin.'
Paddy's mouth dropped. 'Oi lived in Martin Street, so Oi did, meself!' he cried. 'And Oi left the Sacred Heart School in 1960. No, no, I tell a lie -- 'twas 1961, for the good Sisters kept me down a year. Not so bright, I wasn't. And then I went into the Bank as a teller, so Oi did. But now, tell me, when did ye come to Australia?'
'I arrived here in 1967,' said Paddy.
'So did I!' cried Dan.
'That's worth another Guiness,' said Paddy. He went over to the bar to buy them.
A woman, who had been listening to their conversation, turned to the barman and said, 'Did you ever hear the like of that? Talk about the long arm of coincidence!'
The barman poured the Guinesses for Paddy, turned to her and said drily, 'Ah, I wouldn't be too surprised at anything the McGinty twins say ....'
