Two English businessmen in London were sitting down for a break in their soon-to be, new store.
As yet, the store wasn't ready, with only a few shelves set up.
One said to the other, 'I bet any minute now some thickheaded tourist is going to
walk by, put his face to the window and ask what we're selling.'
No sooner were the words out of his mouth when, sure enough, a curious Aussie walked to the window, had a peek, and in a broad Australian accent
asked 'What are you selling here, mate ?’
One of the men replied sarcastically, 'We're selling ar**-holes.'
Without skipping a beat, the Aussie said,
'You're doing well ... Only got two left in stock!'
