Reminids me of my brother & I teaching Charlie (now 13), "What sound does the dog make.", and he'd bark. "What sound does the cat make?", and he'd mew. "What sound does the cow make?" (They live on a dairy farm), and he'd moo. "What sound does the rat make?", and he'd point to the ceiling of their trailer 'cuz that where they scrambled around.

Of course, our favourite was, "What sound does Cathulu make?"
