Welsh man walking through a field, sees a man drinking water from a pool with his hand.
The Welsh man shouts:
“Paid a yfed y dwr mae’r gwartheg yn cachi yn y dwr”
(Don’t drink the water, it’s full of cow ****e.)
The man shouts back:
“I’m English ! Speak English, I don’t understand you”.
The Welsh man shouts back:
“Use both hands, you’ll get more in.”
