An Englishman is hiking in Scotland and he pauses to drink from a stream.
A passing shepherd calls out “Dinnae drink frae that, it’s all fulla coo piss an shite!”
The Englishman says to him in a cut-glass accent
“I’m terribly sorry, my good fellow, would you very much mind repeating that in the Queen’s English?”
And the shepherd says
“I’m terribly sorry sir, I was only asking if you would like to borrow this tin cup and get a proper drink?”
