Oh, I remember seeing this some ages ago in 9gag... I always wonder why did people pick these scene of the movie in particular to make the meme... I mean, they are as good as any other, aren't they?
No no, I mean the movie scene... It just doesn't have much special on it, so I think the choice of scene is a bit unusual... Like, any other scene of HP would have the same impact overall... At least in my view.
Oh i get you... , well maybe the one who made the meme's found this particular scene fitting with his idea.( The Reaction of hermione)
... Isn't one of her parents, her dentist? I could swear it was implied and I'm basically positive they are dental hygienists.
