Hermione: Ancient Egyptians used to worship cats, you know.
Ron: Yeah, along with the dungbeetle.

Ron: I'm warning you, Hermione! You better 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. It's all right, Crookshanks, just ignore the mean little boy.

Ron: [sitting bolt upright in bed] Spiders ... the spiders ... they want me to tap-dance. And I don't want to tap-dance!

Hermione: Beautiful day.
Ron: [sarcastically] Gorgeous ... Unless of course you've been ripped to pieces.

Hermione: [after Hagrid gives Ron Scabbers back] I think you owe someone an apology.
Ron: Right. Next time I see Crookshanks, I'll let him know.
Hermione: [annoyed] I meant me!

Ron: [looking at Lupin who has just turned into a werewolf] Nice doggie... nice doggie...

[Hermione looks at Ron's broken leg] Hermione: Ow! That looks really painful.
Ron: It's sorta painful. They uh, they might... chop it.
Hermione: I'm sure Madame Pomfrey will fix it in a heartbeat.
Ron: It's too late, it's ruined. It'll have to be chopped off.

[when Harry and Hermione go into the hospital wing after disappearing there]
Ron: Hey, how are you there, if you were just there, and now you're there... Wuh?
Hermione: Ron what are you talking about?
Harry: Yeah, you know it's impossible to be in two places at once!
[Harry and Hermione smile at each other]

Ron: [to Harry] Shes gone mental, Hermione has! Not that she wasn't always mental, but now it's out in the open for everyone to see!
