A Paddy walking through a field sees a man drinking water from a pool with his hand.
The Paddy shouts " Na ol an t-uisce, ta s lan de chac bo " (Don't drink the water, it's full of cowshit.)
The man shouts back " I'm English, speak English, I don't understand you " .
The Paddy shouts back " Use both hands, you'll get more in. "
