A flock of sheep are grazing in a field, happily going "baa baa" to each other and discussing life as usual when suddenly they hear a "moo mooooooooooooooooooo!"

They look around and see only sheep. They carry on grazing as before.

"Moooooo mooooooooooo mmmoo!"

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!"
