Ron: I'm warning you Hermione! Keep that bloody beast of yours away from Scabbers or I'll turn it into a tea cozy!
Hermione: It's a cat, Ronald! What do you expect? It's in his nature.
Ron: A cat? Is that what they told you? It looks more like a pig with hair if you ask me.
Hermione: That's rich! Coming from the owner of that smelly old shoe brush. Too right, Crookshanks, just ignore the mean little boy.
