It is a ROCK.
Not a toy. I spent a small fortune buying you squeaky toys, balls, flying discs, and plush toys. Why do you only want the rock I dug out of the garden?
It isn't even a pretty rock. It doesn't bounce. It doesn't squeak. And mommy can't throw it very far.
And even if she could, she wouldn't. What if it hit you? That rock is bigger than your skull. And as hard-headed as you seem, I'm quite sure the rock is harder.
Frankly, my dear puppy, I do not see the appeal.
