The Sweets

An Englishman, an Irishman and a Scotsman went into a sweet shop together.
I'll have 20p worth of those sweets up there,' said The Englishman, pointing to ajar on a high shelf. So The shopkeeper got out his ladder, climbed up, took down The jar of sweets and gave The Englishman 20p worth, climbed The ladder, and put The jar back up again.
'Now what do you want?' he asked The Scotsman.
'I want 20p worth of those sweets also,' said The Scotsman, so The shopkeeper again got out his ladder, climbed up, gave The Scotsman his 20p worth and was just about to climb back up again when he said to The Irishman, 'I suppose you want 20p worth of those sweets too?'
'No,' said The Irishman. So The shopkeeper climbed up The ladder, put The jar away, climbed down The ladder, and put The ladder away.
'Now,' he said to The Irishman, "what do you want?'
'10p worth of those sweets,' said The Irishman.
