the winner is konasurfing! Oh hang on, he seems to have disappeared yet again...

In that case the winner is
greenleader for:
"roll up, roll up, self serve donkey milk, 10 rupees a cup."

Thanks for all the entries. Some of them I didn't get until I re-read them a second time and they were quite witty. Some of them were pretty funny straight away.
A few I liked off the top of my head were:
"At lunch time , Francis liked to relax with a nice glass of merlot and watch the local market festivities....."
"little did abdul know that he was about to be ass-ass-inated"
"... and so I said to the genie, I want to be hung like a Donkey."
Thanks, and over to greenleader for the next one..
