Two Scotsmen - businessmen in glasgow - were sitting down for a break in their soon-to be new store in London. 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 wise arse idiot 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 cockney walked to the window, had a peek, and in a broad London accent asked

'Wot yer sellin' 'ere?

One of the men replied sarcastically,

'We're selling arse-holes.'

Without skipping a beat, the Cockney said,

'Yer doin' well .... Only two left!
