An Englishman is hiking in Scotland and he pauses to drink

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?”
