Green vegetables

Sandy said to his friend Ron, 'My wife sent me to the greengrocer's to buy some green vegetables."

'So were you able to find some?" asked Ron.

'Well, when I reached the shop, I asked the manager, 'My wife wants some green vegetables. Have they been sprayed with any harmful chemicals?''

Sandy continued, 'The shopkeeper told me, 'No, why don't you do it yourself.'
