Kevin: Sheep have fur.
Me: No, sheep does not have fur! Sheep have fleece.
That's right, sheep's fur provides us with fleece.
No, sheep's fleece provides us with wool.
NO!! Sheep's fur provides us with fleece!! Wool is from cotton.
No, cotton is from worms!!! DUH!!
Cotton don't come from worms; SILK comes from worms. Cotton comes from plants.
... Oh. Right. Well then, where does wool come from?
Told you it came from sheep.
