I Cant Hear You

An Englishman, an Irishman and a Scotsman were in a noisy pub one evening.
'Will you lend me £10?' The Scotsman shouted to The Irishman.
'You'll have to speak up a bit,' said The Irishman, 'I can't hear a word you're saying with all The noise in here.'
'Will you lend me £10?' screamed The Scotsman at The top of his voice.
'It's no use,' said The Irishman, 'I still cannot hear a word you're saying.'
'Look,' said The Englishman,' standing beside them, 'I can hear him quite clearly.'
'In that case,' said The Irishman, "you lend him The£10.'
