A flock of sheep are grazing in a field, happily going "baa baa" to one another and discussing life as usual when suddenly they hear a "moo mooooooooooo!"
They look around &see only sheep. They carry on grazing as before. "Moo moo!"
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!"
