Two men were scuffling outside a pub when along came a huge Irishman - fists like hams - who started taking his coat off.

'You're fighting about Ireland, aren't you?' he demanded.

'No, no,' said both men in unison. 'Honestly, it's a personal matter, nothing to do with Ireland at all.'

'Huh,' muttered the Paddy, and shuffled off. Two seconds later he was back, tearing off his coat saying:

'So Ireland's not worth fighting about, eh?'
