A wee joke

A man is cupping his hand to scoop water from a Highland burn.
The Gamekeeper shouts,

'Dinnae drink thon waater! It's foo ae coo's keech an' pish!'

The man replies,

'My Good fellow, I'm English. Could you repeat that in English for me.'

The game keeper replies,

'I said, use two hands - you get more that way!!!'
