Living in the countryside, as I do, you pick up various farming and wildlife stuff. For instance, the little white cows you see in fields are called 'sheep'.
Regarding sheeps, farmers are a secretive lot. I asked one: "How do you count your sheep without falling asleep?". All I got in response was a funny look and silence. It's obviously a secret never to be told [except to other farmers].
