The sheep were standing around talking to each other and discussing life as usual when suddenly they hear a "mooooooooooo".
They look around and see only sheep. They carry on grazing as before. "Mooooo, moooooo, mmmooo!"
One sheep can hear it all too clearly next to him. He shuffles away a little from his friend, a worried look on his face and then asks, "George, why are you mooing? You’re a sheep. Sheep go 'baa!'"
His friend replies gladly, "I know, I thought I would learn a foreign language!"
