Three sheep are in a field.
The first sheep turns to the others and says, "Baaahhh."
The second sheep responds, "Baaahhhhh."
But the third sheep says "Mmooooooo."
"Wait! Why did you say 'moo'?" asks the first sheep.
"Yes, yes, why did you say 'moo'?" asks the second sheep.
And the third sheep replies, "I'm learning a foreign language."
